With three small people to feed who are obsessed with yoghurt, I was spending a mortgage repayment on tubs of the stuff each week. I have tried all the yoghurt makers out there and have, time and again, been left with a weird, watery mess, or something mouth-cloyingly sweet that was no better than the shop-bought stuff. Enter the slow cooker. My mind was blown. I’ll admit, it’s a bit fiddly to start with, but once you’ve made it a few times, you won’t even blink.

Add the , , and , if using, and whisk to combine. Keep the bowl in the cooker as this is the perfect warm hug that it needs, then cover with the lid. You want to ensure it stays in a warm place for at least 8 hours, around 40°C (104°F) or just over. Alternatively, you can wrap your slow cooker in a towel and pop it somewhere draft free for 6–8 hours. If the yoghurt still seems a little runny, you can incubate it for another 4–6 hours.
Strain it using a piece of muslin (cheesecloth) to eliminate the extra whey. At this point, you can return the to the slow cooker and let it sit for an additional 2 hours to achieve an even thicker consistency.
Add 100 g (3½ oz/1 cup) powdered milk to the quantities below for a thick, luscious Greek-style yoghurt.
If using alternative milks, such as nut or oat milk, you will need to add sugar for the bacteria to activate, and you will need some yoghurt culture. You can find this online or at some gourmet grocers.
