Tzatziki is a classic Greek spread made with yogurt, cucumber and fresh herbs. This recipe is adapted from San Francisco's popular Greek restaurant Kokkari, where it’s a popular starter. 

To make it, start with 1 large English cucumber, 2 scallions, about 2 cups Greek yogurt, 1/4 cup olive oil, a bunch each of fresh mint and dill, a small garlic clove and a lemon.

Peel the cucumber. The skin is slightly bitter and would also impart an unpleasant color to the final product.

Slice the cucumber in half, and scoop out the seeds with a large spoon. Try to scoop out as much of the watery membrane as possible, while retaining the denser flesh of the cucumber.
