Greek-style courgette fritters with tzatziki

Method

1. Top and tail the courgettes, then slice them, diagonally, into 6-7mm thick slices. Toss in a bowl with a little salt, spread out on kitchen paper, then leave to drain for about 30 minutes. Sift the flour and the ½ tsp salt into a bowl, make a well in the centre, then add the 5 tbsp olive oil with 150ml cold water. Gradually beat together to make a smooth batter. Leave to rest.
2. For the tzatziki, peel and discard half the cucumber skin in strips, leaving the rest. Coarsely grate the cucumber. Scoop up small handfuls and squeeze out most of the excess liquid. Tip the yogurt into a bowl and stir in the grated cucumber, garlic, spring onions, dill or mint, olive oil, vinegar and salt and pepper to taste. Spoon into a serving bowl and garnish with a little extra chopped dill or mint.
3. Pat the courgette slices dry with kitchen paper. Heat some oil for deep-frying to 190°C (or until a cube of bread turns golden in 20 seconds). This can be in a thermostatic fryer, deep saucepan or sauté pan.
4. Whisk the egg whites in a bowl until they form soft peaks, then carefully fold them into the batter. Dip the courgette slices a few at a time into the batter, add them to the hot oil and deep-fry for 2 minutes until crisp and golden. Drain briefly on kitchen paper, sprinkle lightly with a little more salt if you wish, and serve with the tzatziki while they’re hot and crisp.
