Step 1

If the cheese is wet, strain overnight in the refrigerator using a cheese cloth, kitchen towel or coffee filter.

Step 2

Beat butter and sugar until light and fluffy.

Step 3

Push the egg yolks and cheese through a strainer placed over the bowl (not really necessary when using store-bought ricotta).

Step 4

Add sour cream and vanilla, then beat until combined.

Step 5

Fold in raisins and lemon zest, adjust the flavor with sugar or lemon as needed, then transfer to a cloth-lined mold (anything with holes or open bottom works, as well as a paper towel or coffee filter if you lack an appropriate piece of fabric).

Step 6

Leave to strain in the refrigerator with a light weight on top for 2 - 3 days.

Step 7

Decorate with colorful sprinkles, candies or edible flowers and serve, preferably with Kulich bread (my recipe here).
