Layer the base of a glass pan or bowl with the coffee syrup soaked sponge fingers. If you want you can even line the glass pan or bowl with a butter paper or parchment paper. Now take half of the mascarpone cheese and cream filling. With a spatula spread it evenly on the sponge fingers. Remove from the heat and stir in mascarpone and vanilla and let custard cool to room temperature. Whip cream with an electric mixer until stiff peaks form. Gently fold into the cooled custard. In a small bowl, combine coffee and Kahlua. Dip ladyfingers in coffee mixture, turning in the liquid 2 or 3 times. Remove it from the fridge and give it a whisk or use an electric mixer to bring back the creaminess, then gently fold in a little mascarpone at a time until smooth. If the mixture is too thick then add a small amount of fresh cream. If making a layer with whipped cream then whip the cream until stiff peaks form. Mascarpone is a curd cheese made of cream that has been curdled by adding tartaric acid for thickening. Mascarpone has a sweeter taste than creme fraiche. It is more solid and therefore added to fillings of savory dishes and desserts such as tiramisu where a thick, not at all runny consistency is required. Creme fraiche, on the other hand, is In a medium pot add the yolks and sugar, whisk together until combined, then whisk in the flour and vanilla, place the pot over low/medium heat. Pour the warm cream mixture into the egg mixture, and whisk continuously until thickened. Whisk the melted chocolate into the thickened pastry cream until combined. . It is best to use heavy cream that has at least 35% fat content. This is because the higher the fat content, the thicker the cream and the more stable the final product. If you can't find heavy cream, you can use store-bought whipped cream, but it won't have the same texture. Whipped cream is much lighter and airier than heavy cream. If you are insistent upon substituting something for the cream, you are probably going to need to experiment with adding some soy lecithin (to make sure that the substitute fats don't separate), maybe some cold-soluble gelatin too for added stabilization (regular gelatin that has been bloomed and added when the mixture is hot might also work), and possibly a few other gelling or thickening agents. How To Make Homemade Tiramisu. Take the Mascarpone out of the fridge and let it come up to room temperature while making the custard mixture. Combine egg yolks and sugar in the top of a double boiler, over boiling water. Beat the cream until stiff. Set aside. Step 6. In another new mixing bowl, mix Mascarpone Cheese (1 cup) with egg mixture. Step 7. Add the whipped cream mixture to the egg and mascarpone cheese mixture. Fold in gently. Step 8. In a small bowl, prepare espresso liquid by mixing the Espresso Powder (1 Tbsp) with water. Let cool on the counter. Immediately start beating the mascarpone cheese and sugar in a stand mixer fitted with the chilled bowl. Whip on low speed until it loosens up. Add chilled cream, increase to medium and keep whipping until beater starts leaving tracks inside the cream. Check on the gelatin.
