I've used my friend Ryan's truffle recipe for the 'Dung Ball' but you can use any hard to the touch truffle ( such as this awesome instructable ). If you can easily pick it up, then you can use it for a dung ball.
Step 1: Gather your beetle makings.
A dung ball. Or a truffle center. :)
Almond Paste - Note that I didn't have marzipan, so I used almond paste. They have the same ingredients (almonds, sugar and glucose) but in slightly different proportions. If you use marzipan rather than Almond paste, skip step 2.
Powdered sugar - Maybe half a cup. If you are using marzipan, rather than almond paste, you'll need even less. It's the marzipan equivalent of dusting your hands with flour.
A bit of water
Something sharp for pattern making
