I want to make a gallon of homemade buttermilk.?
I don't know the exact portion for a gallon, but if it's regular milk powder, you add a tbsp of lemon juice or vinegar to the cup to make buttermilk substitute.

Reply:Store-bought buttermilk has a live culture in, so you can use ordinary milk, just mix and leave it for a day or two.



The best way is to make some butter, this is easy to do with a food processor, just take a pint of unpasteurised cream and make whipped cream (no sugar) and leave the mixer on. After another 10 mins, it becomes like scrambled egg; this is butter. You drain the liquid, and ad it to ordinary milk and again leave for a couple of days. The butter should be washed to remove any remains of the buttermilk, and can then be patted into a block. The best buttermilk comes from unpasteurised cream as the pasteurisation kills a lot of the bacteria you want, which is why store-bought buttermilk has culture added.



You can buy the cultures needed for buttermilk from websites who sell cheese-making supplies.
