In a medium mixing bowl, grate the cucumber into small pieces. Wrap the cucumber in a paper towel and carefully drain excess water, squeezing out as much as possible.
Return the cucumber to the bowl, along with the rest of the ingredients. Whisk together until everything is combined.
Pour into an airtight container and refrigerate, or serve immediately.
Notes
StorageRefrigerate for 2-3 days in an airtight container. The cucumbers might release some more water while it's in the refrigerator, just give it a good stir.I don't recommend freezing, because the texture will change too much.Cooking Tips
Grate the cucumber, then wrap it in a paper towel or clean kitchen towel, and squeeze as much of the water out as possible.
If you want your garlic to be less intense, after mincing the garlic let it rest in the lemon juice for a few minutes before mixing it in.
If you don't want to shred the cucumber manually, you can also do it with a food processor. You'll still have to drain the cucumber before adding it to the sauce.
This tastes best when it has a chance to rest in the refrigerator for at least 30 minutes and served cold.
