Steam Cooking Boilies: The Best Way to Preserve Attraction
Today’s article is dedicated to steam cooking — in my opinion the best cooking method for producing high-performance boilies without destroying the valuable water-soluble ingredients added to the mix.
The subject is covered in a more technical way in the “How to Make Boilies” section on the website, but here we’ll keep things simple and practical, as usual in these Bait Guru articles.
Why Steam Boilies?
Steam cooking works without direct contact between the bait and boiling water.
The boilies are placed inside stacked baskets positioned at least 5cm above the water surface. This allows the bait to cook gently through steam rather than by immersion.
The main advantage is simple:
You preserve far more soluble attractors, amino acids and liquid ingredients inside the bait.
Boiling, on the other hand, washes away part of the most valuable soluble fraction.
Equipment Needed:
Pot
An aluminium pot is ideal because it heats quickly and maintains temperature efficiently when opening and closing the lid.
Wider pots are generally better than tall narrow ones because they allow you to use larger baskets and cook more bait evenly.
One of the most critical moments during steaming is opening the lid to insert the baskets.
If you use too many small baskets stacked vertically, steam temperature drops significantly and the upper layers often cook less efficiently.
Burner
A single-flame propane burner is ideal, especially in cold weather.
Always use certified equipment with proper gas pressure regulators.
And most importantly:
NEVER improvise with gas equipment. Safety first.
Baskets
Galvanised mesh baskets work well, although stainless steel is even better.
The mesh should be fine enough not to mark or deform the boilies.
For example, if producing 15mm baits, the holes should be smaller than 1cm.
Clay Pot Spacer
The classic terracotta flowerpot works perfectly as a spacer for the first basket.
It keeps the bait at the correct distance from the boiling water.
Thermometer with Probe
A simple thermometer with a cable probe is extremely useful.
It allows you to monitor both:
* Steam temperature
* Internal boilie temperature
This becomes very important with technical mixes.
The Steam Cooking Process
Start by adding a small amount of water to the bottom of the pot.
Place the terracotta spacer inside, making sure the water level remains 4–5cm below the top of the spacer.
Bring the water to a boil with the lid closed and the flame high.
Once boiling, quickly insert the baskets and close the lid immediately to minimise heat loss.
Reduce the flame slightly to maintain a gentle and stable steam production.
For many birdfood mixes, steam temperature should remain below 90°C.
Higher temperatures can cause some ingredients to swell excessively and trap air inside the bait, making boilies lighter and less stable underwater.
Approximate Cooking Times
Cooking times depend heavily on the mix composition.
High-starch mixes generally require longer cooking times, while highly digestible protein mixes often cook faster.
As a general guideline:
* 10mm boilies: 2–4 minutes
* 15mm boilies: 3–6 minutes
* 20mm boilies: 5–9 minutes
* 24mm boilies: 6–10 minutes
* 30mm boilies: 15 minutes or more
With large boilies, it’s always advisable to cut one open and check the centre before removing the batch.
Steam Cooking for Large-Scale Production
One major advantage of steaming is the ability to cook very large quantities of bait simultaneously.
For large-scale production, however, the mix must be specifically designed for this type of processing:
* Well homogenised
* Finely micronised
* Thermally stable
* Structurally consistent
Classic ECO-style birdfish and fish mixes are perfect for this application because they combine starch-rich bases with robust nutritional ingredients.
In professional setups, the standard pot is replaced with a much larger steel container capable of holding multiple large baskets.
A powerful propane burner is used underneath to maintain stable boiling conditions.
Using Temperature Probes Correctly
When cooking multiple layers of bait, it’s often best to start from cold water rather than adding baskets later.
A probe thermometer inserted directly into a sample boilie allows precise monitoring of the internal core temperature.
Generally speaking, a birdfish boilie is properly cooked when the centre reaches around 60°C.
However, every mix behaves differently.
The best method is always to run small preliminary tests before cooking large quantities.
By recording temperatures and cooking behaviour for each recipe, you can gradually build your own precise cooking reference table.
What Happens If the Baits Are Undercooked?
No problem.
Simply bring the water back to boiling temperature and steam the boilies again for another 1–2 minutes.
With robust feeding mixes, slight overcooking is rarely a serious issue.
However, if you are working with expensive experimental mixes rich in milk proteins or hydrolysates, it’s much safer to cook small batches carefully and avoid unnecessary risks.
