Take 5-6 apples, wash them, remove the core, and blend the apples into a purée!
Place in a clean jar with a loose lid (it should have a little air) and leave it on the table (not too warm, otherwise it will mold) for 5-6 days.
Stir it 1-2 times every day.
When it gets darker, smells like dark beer, and rises a few hours after stirring, it is ready for use!
