Step 1: Pour 4 cups of whole milk into a heavy-bottomed saucepan.
Step 2: Place the saucepan over medium heat and gently warm the milk, stirring occasionally.
Step 3: Once heated, remove from heat and stir in 2 tablespoons of white vinegar or lemon juice.
Step 4: Cover and let sit for 10-15 minutes until thickened and curds form.
Step 5: Line a fine mesh strainer with cheesecloth and pour the curdled mixture into it. Let drain for 30 minutes to an hour.
Step 6: Transfer the ashta to an airtight container and let cool to room temperature before refrigerating.
Step 7: Chill for a few hours before enjoying on its own or in recipes.
Notes
Store ashta in an airtight container in the refrigerator for up to a week. If it thickens too much, stir in a bit of milk to reach desired consistency.
