To make the tzatziki, first peel 1 cucumber. Remove the seeds, then cut the cucumber into ¼-inch (.6 cm) pieces. Peel and crush 1 clove of garlic. Then, combine the cucumber and garlic with 1 cup (245 grams) of Greek-style plain yogurt in a medium bowl. Chop 2 Tbsp (30 g) of fresh dill, then add it to yogurt along with 2 Tbsp (30 ml) of freshly squeezed lemon. Season the mixture with ½ tsp (2 g) kosher salt and ¼ tsp (1 g) freshly ground black pepper. Finally, taste the sauce to see if it needs more seasoning, such as lemon or salt. Serve the sauce with toasted pita or pita chips of your choice, garnished with more fresh dill. For more tips, including how to make chunky tzatziki, keep reading!
