1 cup full fat Greek yogurt
2 cucumbers (the short type)
4/5 cloves garlic
S & P
Splash each of olive oil and vinegar
Crush the garlic cloves into a bowl, add the yogurt. Grate the unpeeled cucumbers and squeeze gently to remove excess liquid and add to the yogurt. Add seasoning, vinegar and oil, stir well and it`s ready.
Having been caught out without any cucumbers, I`ve made it umpteen times without them, and I now prefer Tzatziki without. You can add chopped dill if desired.
