5 large Lebanese cucumbers, trimmed, cut into 5mm-thick slices
2 small brown onions, halved, thinly sliced
1 tablespoon salt (this will be rinsed off)

215g (1 cup) caster sugar
2 teaspoons mustard seeds
2 teaspoons coriander seeds
Large pinch of ground turmeric
1. Place the cucumber, onion and salt in a bowl. Toss to combine. Cover with plastic wrap. Place in the fridge overnight.
2. Rinse the cucumber mixture in a colander. Pat dry with paper towel.
3. Place vinegar, sugar, mustard seeds, coriander seeds and turmeric in a medium saucepan over medium heat. Cook, stirring, for 3 minutes or until sugar dissolves. Add the cucumber mixture. Bring to a simmer.
