Collect 10 - 12 beautiful elderflower umbels, knock them out or rinse them briefly. Place in a saucepan and fill up with approx. 1.5 liters of water. Briefly wash a large or medium-sized lemon (you can also use two limes), cut into slices, core and add to the pot. Now stand covered for about 24 hours in a cool place (e.g. in the stairwell) and let it steep.
The next day, sift everything through a cloth. Now add the 10 or so strawberries that shouldn`t be soft and cook them until the strawberries have given their red color into the syrup. Then get it out. Now add the gelling sugar and let it simmer, make a gelling test and, if necessary, add citric acid or possibly also gelling sugar. The jelly now has a rosé to orange color and a light elderberry-strawberry flavor.
Immediately pour into jars rinsed with hot water, close and turn over.
