Cut the cucumber into quarters lengthways, then run a knife down the edge to separate the seeds from the cucumber. Discard the seeds. 

Chop the cucumber finely and add it to a bowl with Greek yogurt, finely chopped fresh mint, minced garlic (or garlic paste), ground cumin, salt and pepper.

Stir well and taste - you may prefer to add more cumin, seasoning, or even more mint! Bear in mind that the garlic is uncooked, so don't add too much at the start!

Transfer to a serving bowl, and garnish with a mint sprig and a little paprika.

Store in the fridge until required.
