Mix the cucumber slices in a bowl with salt and marinate for an hour to extract the excess water from the cucumber. This also helps remove the bitterness.

Transfer the slices to a colander to drain the liquid. Using your hands, squeeze the slices tightly to get rid of any excess liquid. Do this twice to get the cucumber as dry as possible.

Place in a mixing bowl, adding the chillies, coriander, and lemon juice. Mix thoroughly, and as always, taste a piece and adjust the seasonings as necessary. Cover with cling wrap and refrigerate until ready to serve.
