milk

Whole milk Raw milk

Choose a whole milk, preferably long-life UHT. Raw (fresh) or pasteurized

milk must be boiled then cooled and needs the skin removing.

– Long-life sterilised milk: UHT wholemilk results in firmer yogurts. Using

semi-skimmed milk will result in less firm yogurts. However, you can use

semi-skimmed milk and one or two pots of powered milk.

– Pasteurized milk: this milk gives a more creamy yogurt with a little bit

of skin on the top.

– Raw milk (farm milk): this must be boiled. It is also recommended to

let it boil for a long time. It would be dangerous to use this milk without

boiling it. You must then leave it too cool before using it in your appliance.

Culturing using yogurts prepared with raw milk is not recommended.

– Powdered milk: using powdered milk will result in very creamy yogurts.

Follow the instructions on the manufacturer’s box.

The ferment

If you have boiled the milk, wait untill it has reached room temperature

before adding the ferment. Too high a heat may destroy the properties

of your ferment.

This is made either from:

– One shop-bought natural yogurt with the longest expiry date possible:

your yogurt will therefore contain more active ferment for a firmer

yogurt.

– From a freeze-dried ferment. In this case, follow the activation time

specified on the ferment instructions. You can find these ferments in

supermarkets, pharmacies and in certain health product store.

– From one of your recently prepared yogurts - this must be natural and

recently prepared. This is called culturing. After five culturing processes,

the used yogurt loses active ferments and therefore risks giving a less

firm consistency. You then need start again using a shopbought yogurt

or freezedried ferment.

Fermentation time

Your yogurt will need between 6 and 12 hours of fermentation, depending

on the basic ingredients and the result you are after.
