100gdark chocolate pastry+ or - full-bodied according to your tastes
Prepare in advance
Preheat the oven to 180° traditional heat. Place a parchment sheet on a baking tray.
In a saucepan, place the unbeaten egg whites, grated coconut, powdered sugar and vanilla. Heat over low heat for a few minutes, stirring so that the mixture blends well. Leave to cool until later.
Fill a piping bag with an 8-pronged fluted nozzle or shape the rocks by hand. Place domes of dough on the baking paper, spacing them out (you can bake twice in succession).
Bake the tray halfway up: + or - 15 minutes, it depends on the size of the domes and your oven. They are ready as soon as they start to brown (if you overcook them they lose their softness).
Remove from the oven, remove them from the paper, and let them cool on a rack.
Option with chocolate: melt the chocolate in a bain-marie. Dip the base of each rock in the melted chocolate. Scrape the bottom over the edge of the container. Place on baking paper until the chocolate hardens.
To prolong the softness of coconut rocks, store them in an airtight container.
Notes
These coconut rocks keep very well at room temperature about 4 days in an airtight container. Care must be taken to place them away from heat and sunlight.
