Fermented kale chlorophyll

This preservation method from days gone by is still used on a large scale when producing sauerkraut. It is particularly interesting to see how this method can be used in modern gastronomy. In this recipe, we process the kale into a strong flavour enhancer with a beautiful colour.

fresh kale



caraway seeds



coarse sea salt




As needed:


black pepper

Preparation method

  • Mix the kale with the caraway seeds, ground pepper, and coarse sea salt.
  • Put the mixture in a preserving jar and heat in a combi steamer at 100°C on full steam for 20 minutes.
  • Store the preserved kale in the refrigerator for three months.
  • After three months, briefly rinse the kale in cold water and blend with the water.
  • Strain the mixture into a pan and heat to 90°C, so that it separates into chlorophyll and water.
  • Then pass the mixture through a cloth. The residue left on the cloth is a chlorophyll with a very unusual flavour.

Serving suggestions

  • Is an ideal flavour enhancer in a potato soup. Garnish with a few drops of chlorophyll.
  • Can also be used as a basic ingredient for a fermented kale mayonnaise.
  • Or as a special flavour enhancer in a main dish with stew.
