Cottage Cheese

• This mild cheese is versatile, a good source of protein, and a common substitute for the pricey curd cheeses. It's generally available in small or large curds, and both work equally well. For best results, try to use cottage cheese within a few days of buying it.

Ricotta Cheese

• Ricotta cheese is a more expensive and sweeter than cottage cheese, and is most often substituted for curd cheeses in dessert recipes. Low-fat and nonfat versions are readily available. All varieties should be used within three to five days of purchase for best flavor.

Cream Cheese

• Cream cheese also comes in full-fat, low-fat and nonfat varieties. It can be a good substitute for curd cheese in savory recipes but is not generally recommended for deserts. Cream cheese can be stored for up to a month, making it an economical choice.
