Knead the fat, sugar, egg, flour and lemon zest into a smooth dough. Wrap in foil and chill for about 30 minutes. In the meantime, beat the egg white until stiff, adding salt, icing sugar and lemon juice. Fold in almonds. Pour the mixture into a piping bag with a small perforated spout and chill. Roll out dough thinly on a floured work surface and cut out flowers (4 cm Ø). Place on two baking trays lined with baking paper.
Spray a ring with the macaroon mixture on each flower. Put some jelly in the middle. Bake one after the other in a preheated oven (electric: 175 °C/ gas: level 2) for about 15 minutes. Take out. Heat up the remaining jelly and spread it again thinly on the jelly stains. Results in approx. 70 pieces
