Awesome culture

It was surprisingly easy to make cultured buttermilk with this starter and with your recipes. In these trying times making cheese and assorted dairy products has been a fabulous hobby.

Great culture for cheese

I played fast and loose with this culture adding it to my own cheese recipe and process (I also used basic meso and thermo cultures). it added a lovely buttery taste. 10/10 would use again

A versatile culture.

This is a versatile culture. Added to milk, it makes a very thick buttermilk with good flavor for cooking or drinking. Added to heavy cream, it makes a great cultured butter and you are left with the thinner buttermilk. I have also used it to culture milk in some of the many hard and soft cheese recipes. I like to keep it on hand and recommend it for the same reasons.

A buttermilk that is superior to store bought

Start with a qt of whole milk buttermilk (we enjoy our local delivery from Longmont dairy - Colorado). Warm milk (86 deg F) and add one starter packet. Pour into thermos to keep temp steady for about 12 hrs. Then pour back into your qt milk container and refrigerate. We use it for salad dressing, baking/bread, and of course drinking fresh.
