Ganache

Chocolate Sets the Limits

Watch freely — sign in to save your progress.

Swap the chocolate, change the structure

Keep everything in a recipe the same and only swap the chocolate, and the truffle still comes out different. Not because you did something wrong — each chocolate has its own structure. So instead of forcing a one-size-fits-all recipe, you build a base ganache for the chocolate you actually have.

This is the part most people rush

Before you add inclusions, before you chase a “final” truffle, you test the foundation. Knowing this from the beginning gives you a base to stand on, making it easier to use this chocolate in other recipes.

What this lesson is for

This isn't about perfection. It's about awareness.

Every ratio below is a place to begin, not a recipe to finish with.

Three starting points

A softening agent isn't just heavy cream. Cream is a powerful tool, but don't let it be a crutch. Three different pairings, three different ratios — because the chocolate is what sets them.

Dark chocolate

Heavy cream
2 : 1chocolate : agent

The familiar pairing, and the one most online ratios assume.

Milk chocolate

Coconut cream
3 : 1chocolate : agent

More solids and more sugar than dark, so it carries less liquid.

White chocolate

Bacon fat
4 : 1chocolate : agent

Strain the fat through cheesecloth or a fine mesh strainer first.

RememberStarting points are not final recipes.

Chocolate needs to be warmed to integrate with most softening agents, so the easiest way to start is to chop it fine and pour the already-warmed agent over it. But you need to understand your chocolate too: white chocolate takes more to melt, and one part bacon fat to four parts white chocolate won't distribute enough heat to make it work.

Your chocolate, and your softening agent, change your process.

Ganache doesn't need the chocolate to be tempered. It's fine to gently warm chocolate in a microwave to begin the emulsion.

Choose a structure

Once you have a chocolate, you need a target. These are the five base ganaches — multiple applications, all reached by changing your ratio.

Most solidMost fluid
Scoopable / hand rolledProbably where most of you want to aim. Set hard, but you can scoop it and roll it by hand.

The double boiler, at home

This technique does not translate well to larger production, where you have better equipment. For a home kitchen it makes it very hard to burn chocolate — and it gives a distracted cook room to work slowly.

01Find your vesselsA bowl that holds all your ingredients comfortably, and a pot or pan the bowl sits in comfortably.
02An inch of water, medium heatPut about an inch of water in the pan and bring it up on medium heat.
03Weigh into the bowlZero the bowl on the scale, then add your chocolate and your softening agent — for this example, milk and butter.
04Set it over the pot and waitLet the gentle warmth melt everything for you. Low and slow is the whole point of the method.
05Stir slowly to integrateThe colour turns to one solid tone and picks up a shine that reflects more light. That shine means you have your emulsion.
The catch

It can add water and seize the ganache — either from too much steam escaping (turn the stove down) or from condensation on the outside of the bowl. Keep a towel nearby and wipe the base of the bowl carefully when you lift it off.

Then wait 12–24 hours

Cover the bowl or move it to a fridge-safe container and walk away. The chocolate needs that long to set and finish crystallizing, which is what gives you the structure. Stirring it before then can separate it or turn it grainy.

Name the problem, then test

Did your initial ratio work? If not, define what went wrong before you change anything.

Too soft
Increase the chocolate, keep the softening agent the same.
Too firm
Increase the softening agent, keep the chocolate the same.
Broke or split
The emulsion never held — heat, order, or too much liquid at once.
Grainy mouthfeel
Usually water, or a ganache stirred before it finished crystallizing.

Guess too far on purpose

Don't guess the amount you think is right. Guess an amount you think is too much — your outlier. Now the answer is trapped between a base you know is too soft and an outlier you know is too firm. Make one more in the middle, and taste the middle against the outlier.

  1. Made 1st · too softYour baseThe batch you already made. You know it is too soft.
  2. Made 3rd · taste thisThe middleHalfway between the two. This is the one you taste first.
  3. Made 2nd · too firmThe outlierDeliberately too much chocolate. It should come out too firm.
Reading your results
If the middle came out too firmYour answer sits between your base and the middle.
If the middle is too soft but the outlier is too firmYour answer sits between the middle and the outlier.
If even the outlier is still too softYou did not reach far enough. The outlier becomes your new base, pick a new outlier further out, and split again.

Every round cuts the range in half. That's how you land on your number in three or four tests instead of twenty.

Test in grams
Don't test with pounds of chocolate. You're looking for one or two truffles, not fifty.
Respect scale error
Cheap home scales can be off by 1–2 grams. Your lightest ingredient should be 4 grams or more, then scale the ratio from there.
Change one thing
Measure the same way, test the same way. Change everything each time and you learn nothing about what caused the difference.

What to have in front of you

For the experiment you'll want a white, a milk and a dark chocolate — small amounts of each.

Experiment · one ratio, three chocolates

Ask a search engine for a good ratio for a chocolate truffle. Don't tell it white, milk or dark — just get one ratio. Ask for three and you miss the point. Then make a small batch of each chocolate at that same ratio. Is there a pattern, reading white → milk → dark, and back again?
