Italian Lemon Cake / NO FLOUR, NO YEAST! Melts in your mouth

Ingredients :

300 grams of ricotta
110 grams of sugar
4 eggs
A pinch of salt
150 grams of peeled almonds, ground into a fine powder
Zest of one lemon
2-3 tablespoons of liqueur (Grand Marnier, amber rum, your choice)
Instructions:
Place a clean cloth in a small bowl.
Add 300 grams of ricotta and squeeze very hard, squeezing the cloth to remove the whey. This step is essential to obtain a dry ricotta.
In another bowl, add 110 grams of sugar, 4 eggs and a pinch of salt. Beat until the mixture doubles in volume.
Peel 150 grams of almonds, dry them, then blend them until you obtain a fine powder (no flour, just powder).
