I couldn't believe how ridiculously easy this was to make.
- Take a 1kg tub of Greek yoghurt. Take a large piece of muslin, or, alternatively cheese cloth (makes sense, doesn't it?). Up end tub of yoghurt onto your cheese cloth.
- Draw up the edges of cloth around the yoghurt. Drain as much of the fluid as you can initially then tie a string around it so it's a tight ball. Suspend the ball over a bowl (suggestions from here): tie the ball to a wooden spoon, then rest the spoon on the top of a bowl (or jug!), allowing the ball to hang down. I thought I'd be able to do it with some bamboo skewers, but they couldn't take the weight, even when I used 3-4 skewers. Wooden spoon is definitely the way to go.
- Leave to drain in the fridge for 5 days. You can leave it for less time, but it just tastes like thickened yoghurt. 5-6 days mean it's starting to mature slightly.
