Step 1

In a liquid measuring cup (not the same you use to measure out flour), pour lemon juice or apple cider vinegar.

Step 2

Add enough milk or half and half to make 1 cup of liquid.

Step 3

Stir a few times and let it sit for at least 5 minutes.

Step 4

The buttermilk will thicken and have a chunky texture. That’s perfect!

Step 5

Use it right away or store in the fridge for up to 1 week.
