Lemon soup

What you need for your lemon soup:

4 cups of water
juice from 2 lemons
lemon zest from 1 of the lemons
1/4 cup starch
1 egg
some sugar
and a little piece of a cinnamon stick

Put everything together and boil it. Take the cinnamon stick out of the water after 4-5 min. Take the starch and let everything simmer for a while. In the end just add some sugar to your liking.

While the soup is simmering take the egg whites and add some sugar and whisk it stiff.

You enjoy the soup when it’s cold and as a topping just add the beaten egg whites.
