You will need:
- some chocolate and hazelnut spread
- some cream
Put them in a saucepan. Heat. Stir. Enjoy.
And that's it. You really can get very good results this way, and it's great not having to bother with any of that glass-bowl-over-a-pan-of-boiling-water nonsense usually demanded for melting chocolate. Also, as it takes so little time (two or three minutes), there's no need to prepare it in advance, which is handy.
Perfect with profiteroles, I find.
