For the bees’ antennae: I melted a little milk chocolate. I put it into a piping bag. I used a slate that I’d previously placed in the freezer to make sure it was really cold. I cut the tip of my piping bag very finely and piped rounded lines of chocolate onto it. On contact with the very cold slate, the chocolate sets straight away.
Place two chocolate antennae on each plate, close to the brown marble.
