Ricotta has a short shelf life

By Peggy Trowbridge Filippone, About.com

Ricotta cheese storage

Ricotta cheese is highly perishable. The cheese should be snowy white in color. Yellowing is an indication of age and deterioration. Check the container for an expiration date. Ricotta should always be rerigerated in its container with the lid tightly affixed. Once opened, use within one week.

Ricotta may also be frozen up to 6 months. Defrost slowly in the refrigerator before using.

Ricotta cheese cooking tips and equivalents

  • Discard ricotta cheese at the first sign of any mold. Do not attempt to scrape off the moldy portion to use the rest.
  • 8 ounces ricotta = 1 cup.
  • Dry cottage cheese may be substituted for ricotta in equal measures, but the flavor will be milder and a bit saltier. For some recipes, you may wish to smooth the cottage cheese by putting it through a blender with 1 Tbsp skim milk.
  • Tofu can also be substituted in equal measures for ricotta in many recipes.
  • Ricotta cheese is a good source of calcium. One-half cup provides 42% of the recommended daily allowance of calcium.
