Kefir
Kefir is the sour, lightly fizzy fermented milk that families across Russia, Georgia and the North Caucasus drink plain from a glass at breakfast, as an evening snack or alongside a meal, and also use in pancakes and cold soups. It is made by leaving milk with kefir grains, a living culture of yeasts and bacteria, at room temperature for a day until it thickens. Nothing is added: no salt and no sugar. About 0.25 g salt per 250 ml glass, all from the milk itself. Always use pasteurised milk. The usual mistake is leaving it too long, until it separates into curds and whey; check after 18 hours and stop when it is just thick and pourable. Chef's tip: a second ferment of 6 hours in the fridge in a closed bottle makes it smoother and a little fizzier.
