when
you make tzaziki just grate your pealed cucumber, squize to get rid of reduntant fluid, add a bit of pepper, olive oil, grated garlic (you can use garlic powder or paste too), greek yogurt and mix it all, then finally add about a teaspoon of red wine vinegar, that is how my mom taught me how to make it and she is married to a greek person do not buy the mix cos it ain't the same and never will
