Mix 1 bag each of lemon, woodruff and raspberry jelly powder with 100 g each of sugar in a pot. Stir in 1⁄2 l of cold water each and heat while stirring until the sugar is dissolved (do not boil!).
Divide the jelly into approx. 20 glasses (each containing 100 ml) and chill for at least 5 hours. Whip the whipped cream until stiff and spread as a blob on the jelly. Wash and clean the strawberries.
Put them on as Secret Santa caps and stick on eyes (see tip). Keep cold until serving.
