Place the English cucumber in a fine mesh sieve or clean kitchen towel. Sprinkle with 1/2 teaspoon of salt, toss to coat, and let it sit for 10 minutes to draw out excess moisture.
¾ cup english cucumber, ½ teaspoon salt
Using your hands or the back of a spoon, squeeze the salted cucumber firmly to remove as much liquid as possible. The drier the cucumber, the thicker your tzatziki will be. Set aside.
In a medium bowl, combine the Greek yogurt, fresh lemon juice, fresh dill, grated garlic, and extra virgin olive oil. Stir well until smooth.
1 ½ cups Greek yogurt, 1 tablespoon fresh lemon juice, 2 cloves garlic, 1 tablespoon extra virgin olive oil
Fold in the drained cucumber, the remaining ½ teaspoon of salt, and black pepper. Stir gently to combine.
2 tablespoons fresh dill, ½ teaspoon salt, pinch ground black pepper
For the best flavor, cover and refrigerate for at least 30 minutes before serving to allow the flavors to meld. Drizzle with a little extra olive oil and a sprig of dill to garnish if desired.
