In a liquid measuring cup (not the same you use to measure out flour), pour lemon juice or apple cider vinegar.
Add enough milk or half and half to make 1 cup of liquid.
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.
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.
