For 4 people:
1 cup hazelnuts
4 cups of water
4 dates (to taste)
a pinch of salt
2 tablespoons of cocoa
vanilla extract or bourbon vanilla
Soak the hazelnuts in water overnight. In the morning, drain them and blend together with one cup of water, dates and salt in a blender or other mixer. Gradually add individual cups of water and mix. Strain the resulting mixture through a sieve. Heat the prepared hazelnut milk on the stove and stir in cocoa and a pinch of vanilla. Cook for about 2 minutes (until the desired cocoa temperature).
The recipe is also suitable for immediate preparation (heating is not mandatory).
