1. Gluten-free ladyfingers:
In a bowl, beat 3 egg whites until stiff peaks form, then add 80g sugar. It should resemble a meringue mixture.
2. Next, add 3 egg yolks and beat to combine well.
3. Slowly incorporate the cornstarch into the mixture, being careful not to deflate the egg whites. I recommend using a spatula or wooden spoon for this.
4. Once the mixture is ready, depending on the presentation you prefer, there are two options:
Either pipe ladyfinger shapes onto parchment paper using a piping bag and bake on a baking sheet.
Or, like me, spread the mixture directly onto parchment paper to make a rolled biscuit and bake.
5. Bake the biscuit for 5 to 8 minutes at 180°C in a preheated oven.
6. Mascarpone cream:
First, beat 3 egg whites until stiff peaks form.
7. In another bowl, beat 3 egg yolks with 3 tbsp of sugar until the mixture becomes pale, then add the mascarpone. Using a whisk is easier than a mixer, as a mixer may make the mixture too runny.
8. Gently fold in the beaten egg whites using a spatula.
9. If the mixture seems too runny, refrigerate it for a while to thicken, checking on it occasionally.
10. Once the biscuit has cooled, place it in a gratin dish and soak it with coffee. Then cover it with the mascarpone cream and place the second half of the biscuit on top, soaking it as well. Add a final layer of cream and refrigerate everything. Before serving, you can dust the tiramisu with cocoa powder.
