I make yogurt in a quart mason jar and set it in a cooler with some jugs of warm water. Store-bought plain yogurt with live bacteria works as the starter. I've recently tried 2 varieties of mesophilic yogurt (cultures at room temperature) and it's OK but thinner and less tasty. So back to heating the milk to 180F and cooling it to 115F. I'm eating whole milk yogurt, as it keep you full longer and keep your blood sugar more steady (less urge to snack). If you drain off whey to turn it into Green yogurt, you can use the whey as starter for fermenting vegetables.
I've also been culturing buttermilk - super easy, cultures at room temperature, keeps for a couple weeks in the fridge. Buttermilk is nice in pancakes, muffins, and breads. Also nice for soaking breakfast oats overnight.
Oil is good, grease is better.
