Ricotta cheese, the delicious key ingredient in Italian dishes from lasagna to cannoli, is simple to make in your own kitchen. Homemade ricotta cheese requires just a few ingredients, and the result is lighter and fresher than store-bought cheese. See Step 1 and beyond to learn how to make a batch today.

Ingredients

Milk-Based Ricotta

  • 8 cups whole milk
  • 1 cup heavy cream
  • 1/4 cup distilled white vinegar
  • 1/2 teaspoon salt
  • Equipment: nonreactive bowl, cheesecloth, fine-mesh strainer, saucepan, candy thermometer, ladle

Whey-Based Ricotta

  • Whey left over from making cheese
  • Equipment: nonreactive bowl, cheesecloth, fine-mesh strainer, saucepan, candy thermometer, ladle

Steps

Milk-Based Ricotta

  1. Prepare the strainer. Line the fine-mesh strainer with a large piece of cheesecloth, and set it over the nonreactive bowl. Set this contraption on your work surface so to have it ready for the cheese mixture.
    • If you don't use cheesecloth, it will be difficult to separate the cheese curds from the whey. You can substitute a double layer of paper towels or a thin cotton dishcloth in a pinch.
  2. Heat the milk, cream and salt. Place the milk, cream and salt in the saucepan and heat the mixture over medium-high heat. Allow it to heat until it reaches 200 degrees F. When the mixture is hot enough, turn off the heat and move the saucepan so the milk can begin to cool. It should take about 5 minutes to reach the correct temperature.
    • Stir the mixture as it's heating to prevent it from scorching on the bottom.[1]
    • Use your candy thermometer or an instant-read thermometer to determine whether the mixture has reached the right temperature. If you don't let it cook long enough, the curds won't separate from the whey. If you overcook it, the texture will be ruined.
  3. Slowly add the vinegar. Use one hand to stir constantly while the other hand slowly pours the vinegar into the heated milk and cream mixture. The vinegar will cause the curds to coagulate and separate from the whey. You'll see solid bits forming and floating to the top of the liquid. Keep stirring until all of the vinegar has been added.[2]
    • The curdling agent in this case is vinegar, but some people prefer to use other substances. Try substituting {{safesubst:#invoke:convert|convert}} of lemon juice for a different flavor.
    • For a more traditional touch, try using animal rennet as your coagulant.[3] Mix 1 teaspoon of rennet with 1/4 cup of cold water, then stir it into the milk mixture.
  4. Let the mixture sit until it's thick. Wait about 10 - 20 minutes for the coagulant to go to work and cause the curds to separate from the whey. It's ready when the curds have floated to the top to form a thick layer, leaving the liquid whey underneath.
  5. Ladle the curds into the strainer. Scoop out the thick top layer of curds and ladle them over the cheesecloth-covered strainer. Keep ladling out the curds until all that's left in the saucepan is the whey. You can discard the whey at this point.
  6. Let the ricotta drain. Wait at least an hour for the last of the whey to drain from the ricotta through the cheesecloth into the bowl. It will take about half an hour for the ricotta to fully drain. Don't attempt to stir it or push it through the cheesecloth, as this will just push the curds into the cloth.
    • If you'd like a creamier final product, stop draining the ricotta after 5 - 10 minutes. For a drier final product, wait an hour for it to drain.[4]
  7. Spoon the ricotta into a bowl. The finished ricotta is now ready to use in your favorite recipe. It's delicious as part of a savory dish or a dessert. Ricotta will keep in the refrigerator for about a week.

Whey-Based Ricotta

  1. Save the whey from making cheese in a non-reactive pot. When you make homemade cheese, you'll have curds at the bottom of the pot, and you'll pour off the whey. Filter as many of the curd particles out as you can since they would otherwise form tough "beads" in the final ricotta. Cover the whey and let it sit for at least 12 hours at room temperature to develop sufficient acidity.
    • Acidified whey acts as its own coagulant, making it unnecessary to add vinegar or lemon juice to separate the curds.
  2. Heat the acidified whey. Pour it into a saucepan and heat it while stirring, taking care to avoid sticking or burning. Heat until the temperature has risen to about 175 degrees Fahrenheit and a white appears on the surface. Continue heating and stirring until the temperature reaches 200 degrees Fahrenheit.
    • Note that the foam will build up somewhat. Be careful. If it boils, it can boil over.
  3. Remove the whey from heat and wait for it to curdle. Cover it and allow it to cool undisturbed until comfortable to the touch. The curds will soon appear like clouds suspended in the whey, while the whey will be clear and yellowish green.
  4. Strain the ricotta. Do not stir up the curd. Instead, set up a receiving pot with a large strainer and a fine clean cloth on top. Ladle the curds into the cloth, leaving the whey in the saucepan. Discard the whey.
    • Be sure to scoop out the curds gently. Because the curds are very fine and delicate, they can stop up the cloth easily. This will cause very slow draining if they are broken up.
  5. Drain the whey through the cloth. It can take 2-3 hours for the whey to completely drain. If you prefer, you can set the strainer in the refrigerator and let it drain overnight.
  6. Remove the ricotta from the cloth. Pack it into a container, cover it and store in the refrigerator. Use it soon after making.
    • Ricotta will keep up to a week in the refrigerator. Alternatively, ricotta freezes very well.

Tips

  • This process relies on allowing the inoculated bacteria in whey to further ferment the liquid as it sits at room temperature for an additional 12-24 hours. During that time, the remaining sugars are converted to lactic acid, which lowers the pH of the whey. The solubility of the protein in acidified whey is reduced. Heating the acidified whey denatures the protein causing it to precipitate out as a fine curd.

Things You'll Need

  • Non-reactive pot, either stainless steel or enameled. If you use a thin enameled pot, you should either heat the whey in it over boiling water, or stir nearly continuously.
  • Wooden spoon or long handled spatula (with square end to help to keep curd off the bottom)
  • Thermometer (0-110 °C) to monitor temperature of whey while heating
  • Receiving pot the same volume or greater as cooking pot (a clean plastic bucket will do)
  • A fine meshed strainer to dip out floating curd.
  • Large strainer to suspend over receiving pot
  • Fine cloth (e.g. a clean sterile handkerchief or a non-terry cloth dish towel)
