Instructions

Light Butter Cream

1

Make a meringue by heating the 13 g of water and 30 g of sugar to 118 degrees (you should get small bubbles all over the surface of your syrup).

2

At the same time, beat the 23 g of egg whites with the 8 g of sugar.

3

Then pour the bubbling syrup over the egg whites. Whisk until completely cooled down(several minutes). Set aside.

4

Make the cream.

5

Pour the egg yolks in your food processor's bowl and start whisking.

6

Heat the 30 g of water and 75 g of sugar to 118 degrees (you should get small bubbles all over the surface of your syrup).

7

Then pour little by little the bubbling syrup over the yolks. Whisk until the mixture whitens.

8

Place the butter in another bowl and whisk until very soft. Then add it to the previous mixture. Whisk until smooth.

9

Finally, add the Italian meringue and whisk on low speed to get some air into the cream and make it lighter.

Cover with film and set aside.

Coffee Cream

17

Whip the egg whites and gradually add the 50 g of sugar.

18

Incorporate the egg whites into the previous mixture then gradually add the flour.

19

Spread this mixture across 3 sheets of baking paper so you end up with 3 rectangles each measuring 20x30 cm.

20

Bake each rectangle for 10 to 12 minutes.

21

Then leave to cool.

Chocolate ganache
