Collect the daisies and let them dry for about half a day.
Then put the daisies in a pot together with the water and apple juice.
Add the grated lemon peel and the sliced lemon as well.
Cut open the vanilla pod and add the pulp and the pod itself to the pot.
Bring everything to a boil and remove from heat. Let cool slightly and cover and let stand overnight.
The next day, strain the broth and boil it together with the jelling sugar until it begins to jell.
Pour into previously sterilized jars and seal tightly.
