middle-eastern tzatziki:
take a large colander and line it with a very clean dish towel. put it into a bowl.
dump in one large container of yogurt. cover with the ends of the towel and sit it in the fridge overnight. water will collect in the bottom bowl. toss that. the remaining yogurt will be very thick. that's a good thing. squeeze out whatever extra water you can and set aside for a minute.
chop fine or shred cucumbers. add dill, chopped, to taste. add garlic, pressed through a presser, to taste. the garlic will get stronger as it sits. stir it all around. put it in the fridge overnight. the cucumber will make it thinner and replace some of the water.
serve it as a dip or a salad or part of a lamb wrap, greek-style.
