Pure leftover fun!
You've enjoyed your cauliflower however it is that you did it, but it galls you to throw out all those lovely stalks ... similarly, you have a little leftover fish of some sort: smoked salmon fillet, in my case.
Put them both together and enjoy a practically free starter.
Here's how ...
Soften some onion or leek and garlic in butter.
Shred the cauliflower stalks and toss them in.
Pour over stock and boil until the stalks are fully softened.
Blend well in a food processor or with a hand blender. Blending seems to work better and the longer you do it, the creamer it all becomes ... bet you're glad you used a generous amount of butter in the first place, eh?
Serve out into a bowl, dropping in your leftover fish into the middle.
