Wash and peel the cucumber. Slice it in half lengthwise, scoop out the seeds, and grate it using a coarse grater.

Place the grated cucumber in a sieve or clean cloth and let it drain for at least 30 minutes. This helps avoid watering down your raita.

Finely chop the fresh mint leaves. Peel and crush the garlic clove, and finely dice the onion.

In a large bowl, combine the drained cucumber, chopped mint, lemon juice, cumin powder, garlic, and onion.

Add the yogurt and gently mix everything together until well combined.

Add salt to taste. If you prefer a spicier raita, you can also sprinkle a pinch of cayenne or black pepper.
