Step 1

Mix the milk and the lemon juice or white vinegar in a jar or bowl until well combined.

Step 2

Let the mixture rest at room temperature for about 10 minutes. After this time, the milk will thicken and curdle.

Step 3

Keep leftovers in an airtight container in the fridge for about 3-4 days (time may vary depending on how long the milk you’re using lasts) or in the freezer for up to 3 months.
