First, you need to prepare the brine. To do this, pour cold water into a container, place it on the stove, and bring it to a boil. Add salt and sugar. Remove from the heat and let it cool, then add the honey.
Then, take a separate container for the malt, flour, and mustard powder and mix them until smooth. Once mixed, add the resulting mixture to the brine.
Place the greens in one dense layer on the bottom of a barrel or any other deep container, then you can add the apples, also in one layer.
Layer the apples and greens in this manner. Once the barrel is filled to the top, pour in the brine and cover with a lid. Add a weight.
So, let it sit for about 7-10 days, and then you can put it in the basement!
