First, grate the cucumber on the large holes of a box grater. Run a knife over the grated cucumber until there is fine in texture, but not minced.
Place the cucumber in the center of a clean kitchen towel, then twist the towel to squeezing out as much moisture as you can.
Put the cucumber in a medium bowl. Add the yogurt, herbs, lemon juice, garlic, and cumin, season with salt and pepper, and mix well.
Refrigerate for 1 hour or overnight to get better flavoring blending before serving.
