Easiyo Tips
There's no need to boil UHT. Although UHT doesn’t taste nice to drink it tastes fine as yoghurt…if you use real milk you have to scald it first…ie bring near boiling.
Here’s how to make without mixes…it's a lot cheaper..
a litre of UHT milk (skimmed, semi, or whole, depending on how healthy you want it)
a few tablespoons of skimmed milk powder (if you want creamier/thicker yoghurt – I recommend putting 4 tablespoons in)
2 tablespoons of live yoghurt (must be live, and as fresh as possible - you can use yoghurt from your last batch, but every say 5 or 6 batches, start from fresh with a shop bought live starter.)
3/4 fill the inside jar of the Easiyo (the clear one) with UHT skimmed milk. Then add 4 tblspoons of marvel type stuff (the value one from supermarket is fine) and whisk it in with a fork.
Then add the 2 tablespoons of yoghurt and again use the fork to whisk it.
Then fill it up to the top with UHT milk.
You then basically use the maker in the same way it says (filling the outside flask with boiling water and leaving it for 6 hours or more).
