a heatproof bowl set over a saucepan 
of simmering water, making sure bottom of bowl does not touch water, until chocolate is melted. Stir well. Set aside for 30-40 minutes or until ganache has thickened.

fitted with a 1cm plain nozzle. Pipe 
a little ganache onto 1 macaron, then sandwich with a second macaron. Repeat with remaining macarons and ganache.
