traces of yolk get into the whites — this is key for perfect stiff peaks later.
Step 3: Combine Yolks and Chocolate
Once the chocolate has cooled a bit (it should still be warm but not hot), whisk in the egg yolks one at a time. This adds richness and helps stabilize the mixture.
Step 4: Whip the Egg Whites
In a clean, dry bowl, beat the egg whites using a hand mixer or whisk until they form stiff peaks. This step gives the dessert its signature airy and fluffy texture.
