The main ingredient in a traditional blintz is cheese. Blintzes are thin pancakes or crepes that are typically filled with a mixture of sweetened cheese, often combined with ingredients like eggs, sugar, and vanilla. The cheese commonly used in blintz fillings is farmer's cheese or ricotta, offering a creamy texture that complements the thin outer layer. Once filled, the blintzes are usually pan-fried or baked until golden brown, providing a delightful contrast to the soft interior. Often served with toppings like sour cream, fruit preserves, or fresh fruit, blintzes are a beloved dish in Jewish cuisine, particularly enjoyed during holiday celebrations.
