This homemade Buttermilk Substitute requires only 2 ingredients and is done in 5 minutes! If your recipe calls for buttermilk but you don’t have it on hand, try this substitute. It’s even better!
In a liquid measuring cup (not the same you use to measure out flour), pour lemon juice or apple cider vinegar.
1 tablespoon apple cider vinegar OR lemon juice
Add enough milk or half and half to make 1 cup of liquid.
1 cup whole milk OR half and half
Stir a few times and let it sit for at least 5 minutes.
The buttermilk will thicken and have a chunky texture. That’s perfect!
Use it right away or store in the fridge for up to 1 week.
Notes
Store it as you would any dairy product. It should be in the fridge and keep well for up to 1 week. Since this is a homemade version without preservatives, the storing time is shorter than store-bought buttermilk.
