Yes, you can grate the cucumbers instead of chopping them. Grating the cucumbers gives the raita a thicker, creamier texture as the juices mix more easily with the yogurt, creating a smoother consistency. It’s also a great option if you prefer a less chunky raita. Just be sure to squeeze out some of the excess water from the grated cucumber to prevent the raita from becoming too watery. Whether you chop or grate, both methods work well—it just depends on the texture you're going for!
