Coffee Truffles

I recently received a request from a friend:

Hey Jeremy! I have a request because I know that you know alot about chocolate!! I need a recipe of a soft ganache filling that I can flavour with coffee to pipe inside a chocolate mould to make truffles with runny centers do u know what I mean???

The following makes quite a bit of ganache for piping into shells. You can divide the recipe in half, if you don’t need that many.

For the ganache:

700g whipping cream,

1000g milk couverture,

20g glucose,

This is a good starting point for a pipe-able milk chocolate ganache. As for the coffee flavouring, you can either whisk an instant coffee into the cream just before adding the chocolate, or use a shot of espresso if you have access to an espresso maker. You can also go the coffee flavoured liqueur route, and add about 50g before adding the chocolate.

The strength of the coffee flavour is dependant on personal taste, so feel free to experiment. I’ve also made cappuccino truffles by using white couverture, and increasing the amount by 100g. To use the above recipe for a dark truffle, the cream and dark couverture should be 900g each.

you can change the flavours all you want, but try not to toy too much with the composition. There is a delicate process involved in the recipe formulation that keeps the ganache from separating. Keep in mind that oil and water don’t mix.

Bring your liquids to a boil, then carefully dump in the chocolate. Don’t whisk it at this point! use a rubber spatula to make sure the ganache is blended together, but try to avoid mixing air into it. From here on out, air is the enemy.

Set the ganache aside to cool, and cover with plastic wrap. Make sure there is no air between the wrap and the ganache, you don’t want bubbles. The reason you don’t want air is that air pockets inside the truffle allow space for mold to grow. Being diligent in keeping air out will give your truffles a longer shelf life (they should be good for about 2 weeks).

Once the ganache has cooled to room temperature, it is ready to be piped. Keep it covered if it’s not going to be used right away. Once piped into shells, allow ganache to set, then cap them with tempered chocolate, roll them, and decorate as desired.

Elements of Cooking: Fire

The chemistry behind cooking and baking happens while following a recipe. Most of the chemical reactions that take place between ingredients happens during the initial mixing and blending together of those ingredients. The biggest difference I found between a pastry kitchen, and a restaurant kitchen is how fire is incorporated and utilised in the process of producing the finished result.

Fire in a pastry kitchen is utilised in two ways. The first, and likely the most obvious, is through baking.

Ingredients are mixed together, allowed to react to each other, shaped, and nearly finished before they are put in the oven to bake. The use of fire in this instance may or may not be direct, depending on the type of heat source being used. People traditionally think of baking as happening in an oven, however there are some instances where dough or batter is baked over direct heat. Many flat-breads are baked on a metal dome over an open fire, and pancakes, crepes, and waffles are poured into a pan or griddle over a heat source.

One of my favorite bread related memories happened on a three week canoe trip on the Buffalo River in Arkansas. We made bannock, a traditional Native American bread. We stuck the raw dough on the end of sticks, and baked it over the open flames of the bonfire. The finished result, when spread with homemade strawberry jam, was phenomenal. A raccoon even tried to get in on the action and scared the daylights out of my friend Jere.

The other type of heat generally employed in the pastry kitchen is direct heat in the form of boiling. Whether this takes the form of boiling sugar for confectionery work, boiling fruit for a puree, or boiling water for a bain marie, doesn’t really matter, since it’s the same general idea. Often boiling and baking can occur together in the same recipe, as in the case of a pie, where the filling is prepared by boiling ingredients together, and the crust is baked. 

Fire in the restaurant kitchen, on the other hand, is the nearly alchemical process by which a cook takes a single ingredient and transforms it into something different.

Roasting, braising, sauteing, poaching, grilling, broiling, sous vide, frying, steaming, all have their own unique purpose in the cook’s repertoire. Where a pastry chef follows an exact recipe to bring about a desired reaction, chefs use an exact cooking technique.

Through the application of fire, a cook is able to extract and reabsorb juices. They are able to reduce a liquid and caramelize an ingredient. Using these techniques allows them to concentrate flavours and reintegrate them back into the food.

How well you are able to heat, concentrate, and reintegrate through the use of fire will determing how good you are at cooking.
