Plain yogurt is a great replacement to sour cream on top of tacos, quesadillas, burritos, enchiladas, etc. Stir in some canned chipotle peppers that have been pureed, for a delicious kick. It is also great for a refreshing sauce for Indian & Middle Eastern food, if you mix in some combination of herbs (choose from marjoram, oregano, basil, thyme, black pepper, mint, and/or garlic), chopped onion or chives, and/or chopped cucumber. You can skip the onion and cucumber if desired. Great on gyros, or as a compliment to kabobs or Indian curries & rice dishes.
Alternatively, for a lightly sweet tasting treat without all the sugar in commercial yogurt, stir in a bit of vanilla, lemon & almond extracts (all three together are delicious), add some blueberries and/or other fruit, and optionally add a handful of cashews or almonds, and enjoy! For extra indulgence, add a drizzle of honey on top of the nuts. The nuts are best added right before eating, so they don’t absorb moisture and loose their crunch. The extracts add to the sweet flavor, without adding sugar.
