Worked great for my Camembert

I used the buttermilk starter for my Camembert and it worked great. Now, I’m going to need a lot more practice flipping but that certainly isn’t the starters fault Great product, just like everything else that I’ve purchased from the company.

Fresh Buttermilk!

After struggling with store-bought buttermilk for decades, I decided to make some cultured buttermilk myself using fresh cultures from New England Cheesemaking Supply Company and good, fresh milk. What a difference! The buttermilk was so easy to make. I microwaved the milk to heat it as per the directions, let it cool to 86F, added the culture powder, and blended it in well with a whisk. I then put the mixture in my Yogotherm incubator (you can use a thick tower if you do not have one) and let it sit on the counter overnight. In the morning, I had beautiful, thick, sweet/tangy buttermilk for my Buttermilk Oatmeal Bread, Southern Fried Chicken, and buttermilk sourdough pancakes. Scrumptious!
