Instructions
To prepare the cucumber
Peel the cucumber, then cut it in half lengthwise. Scrape out the seeds using a grapefruit spoon or other spoon.Using the large holes of a box grater, shred the cucumber onto a cutting board. Rough chop the shreds so there are no long strands.Put the shredded cucumber into a fine mesh strainer and it set over a bowl. Sprinkle with a pinch of salt and stir occasionally with a soft spatular or wooden spoon to encourage the cucumber juice to drain. Let it drain in this way for at least 15 minutes.
To prepare tzatziki sauce
In a medium-small bowl, stir together the yogurt, lemon zest, lemon juice, dill, salt, garlic powder, and pepper. When the cucumber is finished draining, fold it into the sauce.
Cover and refrigerate for at least an hour, preferably overnight, so the flavors have a chance to blossom and marry.
Notes
After draining the liquid from the cucumber you're left with cucumber juice. It's delicious and refreshing, so drink it instead of discarding :)
No fine mesh strainer? As an alternative, put the cucumber shreds into cheesecloth and gently squeeze the liquid out.
Tzatziki sauce is traditionally made with dill; however, you can substitute with an equal amount of finely chopped fresh parsley or a lesser amount of fresh mint.
Garnish with chopped scallions if desired.
For those not restricting oil, drizzle a bit of extra virgin olive oil on the surface of the tzatziki when serving.
