Ganache
Inclusions Change the Limits
A third influence enters the balance
In the last lesson, we built a base ganache and learned that chocolate sets the limits. Your ganache began as a balance between two roles: chocolate and the softening role. When an inclusion enters that structure, it introduces a third influence that the original balance was never designed to handle.
Every time you add something new to ganache — even a small amount — you invite change. The texture can shift. The firmness can change. And the flavor can move in unexpected directions. These additions are called inclusions.
The base in all three will not change. But the structure will.
Observe the shift before you attempt to correct or redesign the formula.
Four categories of problems
That new role rarely behaves neutrally. Different inclusions push the structure in different directions — but almost every issue you meet lands in one of four places.
Firmness
Does your end truffle need to be harder or softer?
Texture
Is the texture grainy?
Structure
Is the structure splitting or oily?
Flavor
Is the flavor too strong, or too subtle?
Change isn't failure. It's information.
One common misconception is expecting the base recipe to behave the same way after an inclusion is added. But every inclusion brings something with it — water, sugar, fat, texture — and that will shift the structure you started with.
The ganache behaved differently after the inclusion, so something went wrong.
Nothing went wrong. The structure responded, which is what a structure does.
The texture changed and the firmness moved away from what I expected.
The structure responded. Those changes are part of shaping the truffle you actually want.
Three failures, one base
Today I am going to start off by giving you failures, not successes — because you learn more from your mistakes than you sometimes do from your successes. The chocolate I worked with might be different than yours, and your results may vary, but the concepts will help you drive it home.

Raspberry Truffle
This base worked, but we added raspberry jelly to it and now even after 24 hours in the fridge it has not set. We only changed one item, and we now have a truffle that is too soft.
Experiment · the liquor truffle, tasted three times
Let's make a truffle, not to roll, but just to taste. Find your favorite hard liquor, and check online to make sure its flavors work with dark chocolate. Bourbon is used in this example.
Taste once, then compare against it twice
Make it and taste it immediately. Then put it in a fridge for 24 hours and taste it again. And then try it one more time at 48 hours. What changed? What got stronger?
Where you make the call
The goal of this lesson is not to end with perfection, it's to end with issues, so that you can think on your own. A chocolatier must be able to diagnose issues in their confections, and this is where you begin. Three formulas, one fix each — and you can't see how anyone else answered until you've answered all three.
Still soft after 24 hours in the fridge. What is the first change you make?
- Add more chocolate — more cocoa butter to set against the jam
- Melt the jam in with the softening phase so it fully integrates
- Pull the milk back — the jam is already doing the softening
It tightened the moment the instant coffee went in. Where do you intervene?
- Increase the milk — enough water to bring the sugar back into solution
- Dissolve the coffee into the warm milk before it meets the chocolate
- Add more fat to stabilise the chocolate against the water
Grainy on the first stir. Fat problem, temperature problem, or ratio problem?
- Increase the milk — more liquid phase to hold the extra fat
- Move the peanut butter into the softening phase, not the finish
- Add powdered sugar to absorb the extra fat
Record your formula
Taste, test, observe, and take notes. Those observations will guide the decisions you make next.
