If your summers are extremely hot, try my method of making Yogurt using the ☀️ sun as your incubator. This recipe works best when there’s a heat wave with consistent temps around 90°F-100°F all day. If you don’t have heat waves where you live, you can still make this recipe using a yogurt maker.

Be sure the milk you’re using is Ultra-Pasteurized or UHT, this won’t work with Pasteurized milk. When you warm the milk, don’t heat beyond 120°F or you’ll risk the chance of destroying the yogurt culture. I used small glass pudding jars, but mason jars work well too
