Beat the egg whites very stiff. While continuing to beat, gradually pour in the 60 g sugar. Pour the meringue into a piping bag. Sprinkle about 40 hazelnut-sized dots on a baking sheet lined with baking paper. Dry in the oven with the oven door slightly open at 100 ° C for approx. 1 hour 30 minutes. Let the meringues cool completely.
Make a dough out of flour, sugar, salt, eggs and butter. Preheat the oven to 200 ° C and line two baking sheets with parchment paper. Roll out the dough as thick as the back of a knife and cut out circles with a diameter of approx. 5 1/2 cm. Cut out another 3 cm diameter circle from half of the circles to create a curl.
Put 1 circle and 1 donut together on the baking sheet. Wash the lime with hot water, dry it, rub the peel and squeeze out the juice. Mix both with the raspberry jam. Put about 1/2 teaspoon of raspberry jam in the middle of each biscuit. Bake the biscuits in the oven for about 12 minutes. Let cool on a wire rack.
Melt the couverture, put it in a small freezer bag and cut off a small corner from the bag. Decorate the biscuits with couverture strips and place 1 meringue in the middle of each biscuit in the still moist chocolate. Let the chocolate dry completely.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
