Grate the courgettes on the largest holes of the grater and add to a colander. Sprinkle with 2 tsp of
flaky sea salt (most of this will be drained away later) and toss with your hands to combine. Leave to
drain in the sink for at least 30 minutes. When the courgettes have softened and released quite a bit of liquid, transfer half of the grated vegetable to the middle of a clean tea towel, bunch all the corners together and twist to squeeze out as much liquid as possible. Set aside.
