Peptonised Milk
Ingredients
Directions
Prepare
Pour the milk and water into a clean quart bottle.
Add the zymine powder and shake well.
Peptonize
Place the bottle in hot water (as hot as your hand can bear) for 20 minutes.
Stop the process as soon as the milk tastes slightly bitter.
Boil for 3 minutes to stop further digestion, or keep surrounded by ice.

What each ingredient does
- Milk
- Provides the protein that the zymine enzymes break down, giving the drink its altered flavour and digestibility.
- Zymine powder
- Contains digestive enzymes that break milk proteins into smaller peptides.
The step that matters
Stop the process at the right moment. Enzymes keep breaking down milk protein while it stays warm, so the milk can turn bitter if left too long. Boiling or chilling halts the enzymes, which is why timing matters.
