A winter "pesto"

This didn't look especially beautiful, so no photo, but it was tasty.

1. Take a couple of handfuls of sunflower seeds (raw, unsalted) and crush them up well with a few pinches of salt and several good grinds of black pepper in a mortar and pestle.

2. Zest one orange with a microplane, add the zest to the mortal and pestle and crush together with the seeds a bit.

3. Add enough heavy cream (the "olive oil of the north") to make a pesto-like consistency.

Toss with hot pasta.
