The ferment
For yogurt
This is made either from:
• Store-bought
natural yogurt
with the longest expiry date possible, and
therefore, your yogurt will contain a more active ferment for a firmer
yogurt.
• 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 certain health stores.
• 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 you a
less firm consistency. You then need to start again using a store-bought
yogurt or freeze-dried ferment.
If you boil the milk, wait until it reaches room temperature before
adding the ferment.
If the heat is too high, you can destroy the properties of your ferment.
Fermentation time
• Your yogurt needs between 6 and 12 hours of fermentation, depending
on the basic ingredients and the results you’re after.
