You can use cow’s, goat’s, sheep’s or even camel’s milk. But we don’t recommend coconut or almond milk yogurt for tzatziki sauce. You can easily turn your homemade 24-hour yogurt made with animal milk into Greek yogurt. Have you ever wondered what makes “Greek” yogurt different from regular yogurt? The difference is that Greek yogurt is “drained” to remove the liquid whey, resulting in thicker yogurt. If you’re worried you can’t tolerate dairy yogurt, read here why 24-hour yogurt is different. If you let it drain for 30 minutes to 1 hour, you get the consistency of Greek yogurt. That’s why I like to combine these meatballs with yogurt and cooked, chilled rice. You hear about probiotics all the time: these are the “good” gut bacteria found in fermented foods like yogurt and sauerkraut. The 24-hour tzatziki yogurt sauce makes it a gastrointestinal dish to die for. After all, it’s one of the most healing foods for the stomach: each properly prepared spoonful of yogurt contains 700 MILLION COF per cup. Pour the yogurt on a spoon or in the center of a cheesecloth. The longer you let the yogurt drain, the thicker it will be. You can let the yogurt drain overnight to get the consistency of cream cheese. With this in mind, I challenged myself to come up with new ways to eat yogurt 24 hours a day. Prepare yogurt from animal milk according to the instructions given here.
