200g dark chocolate (70% cocoa)
120ml heavy cream
30g butter
15g sugar (optional)
In a saucepan, heat the cream until it simmers, then turn off the heat.
Stir the chopped dark chocolate into the heated cream until it melts and becomes smooth.
Add sugar if you want a sweeter sauce and butter for a glossy finish.
For the best texture and taste, drizzle over the heated profiteroles.
