Chocolate meringue cake

I really like to cook and eat a variety of sweet food. My favorite culinary recipe is meringue cake. It is about him that I will tell you now. To begin with, whisk the egg whites with just a few drops of lemon juice to a thick foam. Now we gradually introduce powdered sugar, continuing to beat. As a result, we should get a thick smooth mass of white color. We add finely chopped nuts to it and mix gently. Cover the baking sheet with parchment and spread the meringue on it with a teaspoon. Place the baking sheet in a preheated oven to 100 degrees for 2 hours. We proceed to the preparation of the cream. To do this, carefully rub the egg yolks, adding sugar and milk, mix the whole mass thoroughly. On a very low heat, heat the resulting mixture, stir. When the mass thickens, remove it from the fire. Now beat the softened butter. Pour the cooled yolk mass into it and whisk everything. Now we take the chocolate and break it into pieces, drown it in a water bath. Mix the melted chocolate with the cream, add the rum and beat it well. Then we put all this mixture in the refrigerator for 30 minutes. From the finished meringue and cream, we assemble a triangular shape and put it in the refrigerator for 2 hours.
