Step 1

Pour the buttermilk into the saucepan.

Step 2

Heat while sometimes stirring until it reaches about 120F - if you don't have a thermometer just wait until it's so hot you don't want to dip your finger into it any longer.

Step 3

Turn off the heat and add one teaspoon of citric acid (or lemon juice or some rennit). Stir carefully!

Step 4

Let stand for about 20 minutes.

Step 5

Put a cheescloth into the collander and the collander on top of a bowl. Pour the broken apart buttermilk into the cheesecloth.

Step 6

Wait about 5 to 10 minutes until most of the whey is separated, then either press the cheesecloth to remove more whey from the Quark or just put everything in the fridge. After about 2 hours or after a night, the Quark is ready to use.
