Yakult’s fermented milk is very expensive, but cheap and easy to make. Here’s how to make a Yakult style yoghurt drink at home:
- Buy some Yakult (you need to do this to get the yoghurt cultures)
- Add full fat milk (I think this has more nutritional value, although Yakult make their yoghurt drink with semi-skimmed milk). You’re going to want about 20% Yakult, 80% milk, any more milk and it will result in a yogurt drink that isn’t properly fermented, too much Yakult and the drink will be too thick
- Optionally add some sugar, personally I don’t do this. Instead I add squashed fruit juice after the Yakult has been made
- Put the container in boiling water that is up to 2/3 of the size of the container. Put a lid on the water container and wrap in plastic / fleece or some other insultating material
- Leave for 8 hours
You have now make Yakult at home! Remember to save 20% of the homemade Yakult for the next batch, so you don’t have to keep buying more Yakult. Personally, at step 5, I like to add fruit for flavour.
Also, I recommend skipping step 2 and making the Yakult without sugar. If you want to sweeten it up, add sugar afterwards. The reason for this is that you don’t get any sugars carried over to the next batch, making sugar additions hard to measure.
