and it's spelled Tsatziki.. I was close.. here it is:
2 cups plain yogurt
3-4 cloves fresh garlic minced
juice from 1/2 lemon
1 tsp vinegar (plain white)
sat/pepper to taste
put yogurt in a bowl, put garlic, lemmon juice and vinegar.
Peel the cucumber and begin to cut paper-thin slces. If they are thin enough, you peobably won't get a whole circle sliced. If you do, just cut it in half. Put the paper thin sliced cucumbers into the yogurt. Dust with salt/pepper and mix. refrigerate for at least 2 hours before eating. You want the garlic to blend into the yogurt and you want this dip to be as cool and refreshing as can be.
