How about this:
Homemade Ricotta Cheese
Makes about 2 cups (1/2 pound)
I gallon whole milk
1/4 cup lemon juice
Kosher or sea salt
Heat the milk with the lemon juice in a stainless steel or other nonreactive pot over medium-low heat only until the curds separate from the whey; do not let the milk scorch.
Line a colander with three layers of cheesecloth. Pour the mixture into the colander. Bring the ends of the cheesecloth together and tie them securely with kitchen twine. Tie the twine to a wooden spoon handle. Rest the spoon with the cheesecloth over a deep bowl. Depending on the consistency you desire, allow the bag to hang for 2 to 3 hours in the refrigerator. The longer you leave it, the stiffer the curds will become.
When it is ready, unmold the cheese. Season with salt and store in an airtight container in the refrigerator for 3 days. You might also season the ricotta with minced chives or green garlic, cracked black pepper, and a little olive oil.
Ricotta Cheese
2 qts regular milk
3 tbsp distilled white vinegar or 1/4 cup strained fresh lemon juice
Salt, if desired
Pour the milk into a heavy stainless-steel or
enameled saucepan and stir in the vinegar or lemon
juice; set the pot over very low heat and bring the
milk very slowly to a simmer ( a reading of 200F on a
thermometer). There will be fine beads around the
edge of the milk, which will look foamy but will not
appear to be boiling; remove the pot from the heat and
set it, covered, in a spot where the temperature will
remain fairly uniform at a reading between 80 and 100
degrees; (an unheated oven, without a pilot light, is
a good spot) let the milk stand for about 6 hours or
until a solid curd floats above the liquid (the whey);
more or less time may be required, depending on the
temperature of the environment and the characteristics
of the milk; line a fine sieve with doubled dampened
cheesecloth (or better yet, two layers of very
fine-meshed nylon curtain netting, dampened) and set
it over a bowl; dump the curds and whey into the sieve
and allow the whey to drain off until the ricotta is
yogurtlike; if you want a firmer cheese, tie the
corners of the cloth to form a bag and hang it up to
drain further; (in warm weather, the draining might
well be completed in the refrigerator; when the
texture of the cheese is to your liking, add a little
salt (from 1/4 to 1/2 teaspoon) if you wish; store the
cheese, covered, in the refrigerator; it will be at
its best after it has chilled for 24 hours, and it
will keep well for 4 or 5 days. Makes about 1 pound.
