The other day I got carried away and made a lot of ricotta. Because it is relatively low in salt, it doesn’t keep very long – about a week in the refrigerator. Therefore I had to find several recipes to use it up.

Think of ricotta as cottage cheese’s sophisticated older sister, but without a lot of added salt. Most cottage cheese contains about 500 milligrams of sodium per half cup, a hefty hit against the daily 1,500 -2,000 milligrams recommended for Americans. Most ricotta contains about 150 milligrams per half cup, even less if it’s homemade.

Use ricotta in lasagna and other pasta dishes, or mix into a dip or topping for veggies, crackers or pita. Since it isn’t super salty, ricotta pairs well with fruits and berries. It stars in the fancy Italian dessert cannoli, which are pastry shells filled with ricotta, powdered sugar, citrus and chocolate.

If you are adventurous, try making your own ricotta. As with making bread, you need to “babysit” it, but the work is minimal. You just need to be around to follow through. Equipment is simple: a thermometer, a colander and a cheesecloth.

Homemade ricotta

1 gallon whole, nonfat or low-fat milk, not ultra pasteurized

1/4 cup white or cider vinegar or lemon juice

Pour milk into a large pot. Heat until temperature reaches 195 degrees Fahrenheit, stirring constantly to prevent scorching. When the milk reaches temperature, remove from heat. Stir in vinegar or lemon juice, let stand for 10 minutes. The milk should separate into a flaky white solid part (curds) and a yellowish liquid (whey). Line a strainer with a cheesecloth and set over the sink or a large bowl. Pour milk through the cloth-lined strainer. Let the curds drain in the strainer for half an hour. Discard whey. Place curds in a large bowl, separating and tossing with a fork. If it seems overly dry you can add a little milk or cream and fluff it. Cover with plastic wrap and store in the refrigerator until ready to use. Fresh cheese will last about a week.
