This is a traditional Russian "paskha", a cheesecake paste sweet which is made of quark cheese, loaded into a form press (hence the shape) and then presented on a plate. My mother's is amazing, loaded with vanilla bean and almonds.
Eastern European Molded Cheese Easter Dessert (Paska / Paskha)
Paska (also known as Kulich) is a classic Easter Bread. It’s a wonderful Easter tradition shared by Russian and Ukrainian people. This recipe comes from my aunt Tanya and cousin Lena; Easter only comes once a year so don’t panic when.
