Tzatziki is a sauce made out of Greek yogurt and cucumbers. It is often found on gyros and other Greek food. This is the recipe I use to make it.
1 large cucumber, peeled and seeded
6 oz. Greek yogurt
½ clove garlic
½ tsp lemon juice
¾ tsp olive oil
Salt, to taste
Grate or finely chop cucumber. Place in a kitchen towel and squeeze dry.
Put ½ cup of the cucumber in a medium bowl. Add the yogurt, garlic, lemon juice, and olive oil. Taste and add salt if desired.
Mix well. Refrigerate for at least a few hours before serving.
Makes 1½ cups.
There are many different recipes for tzatziki sauce. Some include diced onions along with the cucumber. It's easy to change it up to suit your tastes.
I know that 6 ounces of yogurt seems like an odd measurement, but I wrote it that way because all I can find at the store is 6 ounce containers of Greek yogurt. If you have a whole cup, use a little more cucumber and lemon juice.
The first time I made this I grated the cucumber, but yesterday I was feeling lazy and didn't want to go to the trouble, so I just finely diced it. Either way is good.
