1 (32 oz.) container of plain yogurt (preferably NOT fat-free)
2 regular cucumbers, peeled & seeded
3 cloves garlic, crushed (I usually use a microplane for this)
2 teaspoon red wine vinegar
1 teaspoon fresh lemon juice
1/2 teaspoon dried dill
salt and a little pepper
drizzle of extra virgin olive oil

1 (32 oz.) container of plain yogurt (preferably NOT fat-free)

Strain yogurt using a cheesecloth over a bowl (if you don’t have that, a strainer lined with a coffee filter will work) for several hours or overnight to get out as much moisture as possible.

Shred or grate the cucumbers, place them in a clean kitchen towel, and then squeeze to get rid of as much excess moisture as possible.

Mix together the strained yogurt, shredded cucumbers, garlic, vinegar and lemon juice. Salt and pepper to taste. It’s best to refrigerate for at least 30 minutes before serving, so flavors can meld.

Drizzle a little olive oil over the top before serving.
