NOTE: People in the Eastern Mediterranean have been drinking fermented dairy products like kefir and labneh as refreshments in warm months for eons. They’ve also been enjoying tart, fermented yogurt forever and consider it one of the healthiest foods in the world. This garlic-free iteration of tzatziki, with its delicious and light cucumber and aromatic herbs, is a very refreshing drink, indeed. Cucumbers, after all, are almost all water. It also borders on being closer to a snack than a drink, so if you’re on the go and want something to sustain you for a few hours, this is a great drink to have on hand!
