What can you substitute for sour cream in a recipe?

Plain Greek yogurt: Greek yogurt has a similar tang and thickness to sour cream. Use it in an equal amount to sour cream.

Crème fraîche: Crème fraîche is a French cultured cream that is slightly tangy and has a high fat content. Use it in an equal amount to sour cream.

Mascarpone cheese: Mascarpone cheese is a rich and creamy Italian cheese. It has a slightly sweet flavor, but can be used as a substitute for sour cream in many recipes. Use it in an equal amount to sour cream.

Cottage cheese: Cottage cheese can be blended until smooth to create a sour cream substitute. However, it has a slightly grainy texture, so it might not be suitable for all recipes. Use it in equal amount to sour cream.

Heavy cream and lemon juice: Combine heavy cream and lemon juice in a 1:1 ratio to create a sour cream substitute. The lemon juice will provide the tanginess, while the heavy cream will add thickness.

Milk and vinegar: Combine milk and vinegar in a 1:1 ratio and let it sit for 5-10 minutes. The vinegar will curdle the milk, creating a texture similar to sour cream. Use it in an equal amount to sour cream.

Avocado: Blend a ripe avocado with a little lemon juice and salt to create a creamy and tangy substitute. Use it in equal amount to sour cream.

Keep in mind that these substitutes may alter the taste and texture of your recipe slightly. Adjust the amounts as needed to achieve the desired consistency and flavor.
