When life gives you lemons, you make lemonade, right? So, if life gives me cucumbers, I make cucumber sauce. I can't officially call this tzatziki, because it only has sour cream in it, not yogurt. You could do half and half w/ plain or greek yogurt and sour cream to make it a little more authentic.
2 small cucumbers, peeled and cut into chunks 2 cloves of garlic, peeled 1 lemon, juiced 2T olive oil 1T fresh dill or mint 1 16oz container of sour cream sea salt to taste
Place sour cream in a small bowl. Place garlic in food processor and pulse until minced. Add cucumbers, lemon juice, olive oil and dill and pulse 4 or 5 times. Stir mixture into sour cream. Add salt to taste. Refrigerate at least 1 hour. Overnight is even better.
