If you roll your own bait, sooner or later something goes wrong.
The paste goes too stiff. The sausage splits. The finished boilies crack, dry too hard, lose smell, or simply do not behave properly once they are in the lake.
That does not always mean the whole recipe is wrong. Most of the time, the real problem sits in one of three places: the base mix is out of balance, the liquid phase was handled badly, or the bait was cooked and dried the wrong way.
This page helps you diagnose the fault properly so you can fix the cause, not just the symptom.
Instead of guessing, start with the stage where the problem first shows up. That gives you a much better chance of fixing the real cause rather than just masking the symptom.

If the problem shows up:
- before rolling, look at hydration, binders, cohesion, and liquid levels
- during extrusion or rolling, look at paste consistency, particle size, and pressure
- after boiling or during drying, look at cook time, drying speed, and structural balance
- on the bank, look at density, water exchange, durability, and storage
Quick Guide: Nozzle Sizes for Common Boilie Diameters
Quick Guide: Nozzle Sizes for Common Boilie Diameters
- 8mm boilies — use roughly a 6.5mm nozzle
- 10mm boilies — use roughly a 8.2mm nozzle
- 12mm boilies — use roughly a 9.8mm nozzle
- 14mm boilies — use roughly a 11.5mm nozzle
- 16mm boilies — use roughly a 13mm nozzle
- 18mm boilies — use roughly a 14.5mm nozzle
- 20mm boilies — use roughly a 16.5mm nozzle
- 24mm boilies — use roughly a 19.5mm nozzle
- 30mm boilies — use roughly a 24.5mm nozzle
For a simple14mm dumbell variant, a useful trick is to use a 10mm nozzle on a 14mm rolling table.

Quick Rule Before You Start Fixing Things
Do not change five things at once.
If a batch goes wrong, work through:
- paste feel
- rolling behavior
- cook time
- drying
- lake performance
That way you can isolate the real fault and stop repeating it.
Dough Too Stiff
What is happening
The paste starts off workable, then tightens too much. It becomes hard to gun out, hard to roll, and starts putting unnecessary strain on your gear.
Most likely causes
- slow-hydrating ingredients still pulling in liquid
- too much absorbent material in the mix
- not enough total liquid
- paste left uncovered on the bench
- warm, dry working conditions
Immediate fix
Add a little reserved liquid back in, a small amount at a time, and knead it properly before adding more.
Do not flood it and hope for the best.
Long-term fix
Build the mix so it reaches its proper working consistency after a short covered rest, not the instant it first comes together.
If a bait always goes too stiff, look closely at:
- too much birdfood
- too much biscuit meal
- too many thirsty powders
- not enough plastic support in the mix
- not enough flexibility in the liquid phase
Michigan Notes
In cool Michigan spring conditions, paste often feels fine at first and then tightens after resting. Always let it sit covered for a short time before judging it.
Dough Too Soft
What is happening
The paste slumps, sticks, and will not hold a clean sausage.
Most likely causes
- too much liquid
- under-mixing
- not enough rest time
- too many syrupy or oily liquids
- not enough structural support in the dry mix
Immediate fix
Rest it first.
If it is still too soft, add a little dry base mix back in. If you have used the whole base mix already, correct it with a sensible support ingredient rather than guessing.
Practical options:
- semolina for support
- biscuit meal for moisture absorption
- a little extra milk-protein support if the mix is too cereal-heavy
Long-term fix
Standardize your liquid levels and stop adding everything at once. Hold some liquid back until the paste tells you what it needs.
Sticky Paste
What is happening
The paste clings to your hands, gun, worktop, and rollers.
Most likely causes
- heavy use of hydrolysates or liquid foods
- syrupy liquids like molasses, honey, or liquid yeast products
- too much sticky protein material
- warm paste
- too much oil with weak dry structure
Immediate fix
Let it rest. Cool it down. Keep the bench clean.
A lightly prepared work surface can help, but the real answer is getting the mix back under control.
Long-term fix
Tighten the liquid package and improve the mechanical balance of the dry mix.
Sticky does not always mean bad. Some highly attractive mixes are naturally tacky. The real problem is when they stop being workable.
Crumbly Paste With No Cohesion
What is happening
The paste breaks apart instead of knitting together.
Most likely causes
- too much cereal bulk
- not enough binders
- not enough functional protein
- poor hydration
- not enough kneading
Immediate fix
Knead longer and let it rest covered.
If needed, add a little supportive binder material and just enough liquid to activate it properly.
Long-term fix
Rebalance the recipe.
Usually this means reducing dead, dry bulk and improving the binder-protein side of the mix so the bait forms a proper mesh rather than a dry crumble.
Sausage Splitting During Extrusion
What is happening
The sausage breaks instead of running out cleanly.
Most likely causes
- paste too dry
- poor cohesion
- too much pressure
- coarse particles tearing the structure
- binders not properly activated
Immediate fix
Slightly soften the paste and reduce pressure.
Long-term fix
Use a more consistent mix and avoid unnecessary coarse material in recipes meant for smooth machine rolling.
Sausage Swelling After Extrusion
What is happening
The sausage comes out and then thickens, which throws off the rolling size and shape.
Most likely causes
- paste too soft
- excess pressure
- low-density structure
- too much trapped air
Immediate fix
Reduce pressure and let the paste settle before rolling.
Long-term fix
Standardize the whole system: same rest time, same pressure, same nozzle, same paste consistency.
Paste Breaking Up on the Rolling Table
What is happening
The sausage reaches the table but tears, crumbles, or breaks into sections.
Most likely causes
- poor cohesion
- too much coarse material
- dry outer skin
- over-rolling
Immediate fix
Re-knead the paste and soften it slightly if needed.
Long-term fix
For boilies you want round and clean, keep the core mix finer and use coarse ingredients with care.
Misshapen Boilies
What is happening
The finished baits are oval, flat-sided, rough, or inconsistent.
Most likely causes
- wrong sausage diameter
- poor paste consistency
- too much pressure
- rolling table mismatch
Immediate fix
Correct the sausage size and correct the paste before forcing more through.
Long-term fix
Standardize the full rolling setup:
- same mix style
- same liquid level
- same rest time
- same extrusion pressure
- same nozzle size
- same table
Boilies With a Hole Through the Middle
What is happening
The bait comes out with a central cavity.
Most likely causes
- trapped air
- dry outside and wetter inside
- weak cohesion
- excessive extrusion pressure
Immediate fix
Use the batch as chops, crumb, or free bait if needed.
Long-term fix
Improve cohesion, hydration, and sausage formation. This is usually a process issue and a recipe issue together.
Undercooked Boilies
What is happening
The outer skin looks done, but the inside remains too wet or pasty.
Most likely causes
- boil time too short
- bait size not matched to cook time
- too much trapped moisture in the paste
Immediate fix
Dry them carefully and test them before bagging or freezing.
Long-term fix
Set proper boil times by bait size and mix density, then stick to them.
Overcooked Boilies
What is happening
The bait becomes too hard, loses leakage, and often loses smell.
Most likely causes
- boiling too long
- small baits treated like big ones
- open, soluble mixes boiled like hard feed baits
Immediate fix
Use the batch where a harder free bait still makes sense.
Long-term fix
Treat boiling as part of bait design. The more soluble and open the bait, the more careful you need to be.
Boilies That Lose Smell
What is happening
The paste smells strong, but the finished boilie smells weak after boiling.
Most likely causes
- volatile flavours driven off by heat
- boiling too long
- wrong flavour choice for a boiled bait
- overreliance on aroma instead of food signal
Immediate fix
Use matching post-boil treatment where appropriate.
Long-term fix
Build attraction around food value, solubility, amino-rich liquids, salts, acids, and real signal ingredients first. Let flavour support the bait rather than carry it.
Boilies Sticking Together
What is happening
Freshly boiled baits clump together instead of separating cleanly.
Most likely causes
- poor draining
- over-soft paste
- surface starches
- too many hot baits piled together
Immediate fix
Spread them out fast and dry them in thin layers.
Long-term fix
Get the paste right before boiling and improve your draining and drying routine.
Boilies Collapsing
What is happening
The boilies lose shape after boiling instead of staying round and stable.
Most likely causes
- paste too soft
- weak internal structure
- not enough binder support
- under-cooked bait
Immediate fix
Dry them carefully and separate them well.
Long-term fix
Tighten the mix, improve cohesion, and match boil time properly to bait size and softness.
Boilies Cracking While Drying
What is happening
The outside dries too quickly and the bait splits.
Most likely causes
- drying too fast
- too much rigid dry matter
- not enough internal elasticity
- hot moving air
Immediate fix
Move them to a gentler drying area and stop overexposing them.
Long-term fix
Build more elasticity into the bait and dry it more steadily.
Hard Crust on the Outside
What is happening
The bait forms a shell that slows water entry and leakage.
Most likely causes
- overboiling
- overdrying
- surface sugars or powders hardening
- poor internal porosity
Immediate fix
For hookbaits, trim or skin them.
Long-term fix
Build for water exchange. A good boilie should not just survive in the lake. It should work in it.
White Film on the Surface
What is happening
A pale or whitish coating appears after drying.
Most likely causes
- surface residues
- milk powders or salts moving outward
- drying imbalance
Immediate fix
Check whether it is only cosmetic or whether the bait has genuinely sealed up.
Long-term fix
Tighten the recipe and drying process. Watch salt levels, milk fractions, and total soluble load.
Boilies Too Light
What is happening
The bait feels too buoyant or too airy for the job.
Most likely causes
- low-density mix
- internal holes
- swelling during cooking
- too much trapped air
Immediate fix
Use them where a lighter bait helps, or keep them tight with bags, crumb, or small trap-style feeding.
Long-term fix
Increase density sensibly if the venue demands it.
Michigan Notes
On soft Michigan silt, slightly lighter baits can be useful. On deeper water or when you want tighter baiting, too much lightness can work against you.
Boilies Cracking in the Throwing Stick
What is happening
The baits cannot cope with the shock of being fired.
Most likely causes
- too dry
- too brittle
- not enough elasticity
- old bait
- too much rigid or coarse material
Immediate fix
Use them by hand, catapult, bag, or as crumb.
Long-term fix
Improve hydration, elasticity, and storage so the bait stays tough enough without becoming brittle.
Boilies Swelling Too Much
What is happening
The bait takes on water too fast, softens too much, and loses integrity.
Most likely causes
- poor cook balance
- too much open structure
- weak binder system
Immediate fix
Use them for short sessions or chop them into feed.
Long-term fix
There is a difference between good leakage and structural collapse. Aim for exchange without failure.
Boilies Breaking Down Too Fast
What is happening
The bait leaks nicely but dies too quickly.
Most likely causes
- too soluble for the job
- not enough cooking support
- weak protein-binder network
- too much liquid food and not enough structure
Immediate fix
Use them in colder water, short sessions, or as support bait around a stronger hookbait.
Long-term fix
Balance solubility with hold.
Boilies Floating After Soaking
What is happening
After time in water, some baits lift or remain unnaturally buoyant.
Most likely causes
- trapped air
- internal holes
- overdrying
- poor density
Immediate fix
Use them as chops, crumb, or trim them for another purpose.
Long-term fix
This usually starts earlier in the process with paste cohesion and shaping.
Boilies Going Rock Hard
What is happening
The bait becomes too dry, too hard, and poor at exchanging.
Most likely causes
- excess drying
- too little retained moisture
- poor storage approach
- over-rigid mix design
Immediate fix
Crumb them or use them where extra hardness is useful.
Long-term fix
Dry less aggressively and freeze sooner where appropriate.
Boilies Struggling to Take on Water
What is happening
The bait stays hard and durable, but it never really wakes up in the lake.
Most likely causes
- surface crust
- too much starch
- not enough hygroscopic pull
- overcooking
- overdrying
Immediate fix
For hookbaits, skin them or crack them slightly.
Long-term fix
This is one of the biggest design faults in home-rolled bait. If you want signals out, you must allow water in.
Common Mistakes
- judging the paste too early
- adding all liquids at once
- not resting the paste
- chasing attraction while ignoring mechanics
- using coarse ingredients where fine structure is needed
- boiling every recipe the same way
- drying too aggressively
- confusing hard bait with good bait
FAQ
Is stiff paste always a sign of a bad recipe?
No. Some mixes hydrate slowly and tighten after resting. The question is whether the paste becomes predictably workable or turns into a fight every batch.
Should I add water if the paste is too stiff?
Usually not straight away. It is normally better to correct with reserved liquid phase or improve the recipe and process next time.
Why do my boilies smell strong before boiling and weak after?
Because too much of the attraction is tied to volatile aroma rather than retained food signal.
Are softer boilies always better in cold water?
Not always. Softer, more open baits often leak better, but they still need enough structure to remain useful.
Why do my boilies crack after a day or two?
Most often because they were dried too hard, cooked too much, or built from a mix that is too rigid.
What matters more: recipe or process?
Both. A good recipe handled badly still fails. A bad recipe handled perfectly only hides the weakness for a while.
These are working guides rather than exact rules because final shape can still vary with paste consistency, pressure, and the rolling table itself. Always test a short sausage first before running a full batch.
