A couple of liter/750ml mason jars, an equal quantity of fresh goat milk (along with a big enough pot to pasteurize it all) and a single serving of "probiotic" greek yogurt makes for an awesome homemade goat sour cream as well
.
Heat your goat's milk up to a very low simmer, pour it in your clean jars, and lid loosely. Wash your pot, throw a dishtowel in the bottom, put the jars back in, fill 3/4 of the way up the jars with water. Bring that water to a simmer, and heat for 20m. No bubbles, just a simmer. Remove from heat, cover, and cool overnight. The next morning, add a teaspoon of off the shelf yogurt, and culture for 16, 24, 36 hours for Yogurt, Creme Fraiche or Sour cream.
You can make a nice fresh goats cheese (similar to ricotta) by adding 40ml fresh lemon juice per liter of milk, when hot, stirring for 10m, and straining through cheesecloth as well. Chill asap. Ran that on a menu for almost a year, just stir in salt to taste.
UHT isn't an issue with local goatsmilk obviously, but it's imperative for cowsmilk culturing. 5% is great for either. And yes, you can drink the whey under the curd, but it's awful.
