Authentic Greek tzatziki

Tzatziki is more than cucumber yoghurt. The key is removing water: cucumber is 96% water, which, if left in, turns the sauce into a runny soup. Salting and patient draining concentrates the cucumber flavour and maintains the yoghurt's thickness. The pairing of garlic and vinegar/lemon provides the characteristic 'sharp' freshness.

Instructions

1

Wash the cucumber (skin on), and grate on a coarse grater.

Tip: The skin provides crunch and colour, do not peel completely.
2

Salt the grated cucumber and let stand in a sieve for 10-15 minutes.

Tip: Salt draws water out of plant cells by osmosis. This is a critical step! (Water extraction).
3

Squeeze the cucumber with your hands or a tea towel as hard as you can. It should be almost dry.

Tip: Remaining water would dilute the yoghurt and spoil the emulsion.
4

Mix the yoghurt with the crushed garlic, olive oil, lemon juice and squeezed cucumber.

Tip: Drizzle the oil on at the end for a glossy finish.
5

Stir in the chopped dill, and chill for at least 30 minutes before serving.

Tip: Flavour diffusion (mixing) takes time.

Recipe FAQ

It still turned out runny.
You didn't squeeze the cucumber enough, or didn't use Greek yoghurt. Plain yoghurt is too thin for this.
Too garlicky.
Garlic strength increases whilst standing. If you prefer it milder, use less, or roast the cloves beforehand.
