Can I use low-fat milk instead of whole milk?
Whole milk and heavy cream are essential for ricotta's creamy texture. Low-fat milk will produce thin, watery curds with poor flavor and texture.
What can I use instead of fresh lemon juice?
White vinegar works as a substitute at a 1:1 ratio. Avoid bottled lemon juice, which lacks the acidity needed for proper curd formation.
How long does homemade ricotta keep?
Store in an airtight container in the refrigerator for up to 5 days. It does not freeze well due to separation.
Why are my curds not forming?
The milk may not be hot enough—aim for 185–195°F. Also verify your lemon juice or vinegar is fresh and acidic enough.
Can I scale this recipe up or down?
Yes. Maintain the ratio of 3:1 milk to cream and 1/2 tsp lemon juice per cup of milk. Scaling up requires a larger pot and longer heating time.
