Raw beetroot mousse with walnuts (Slideshow version)
Stage 13/13 :
Finish with some chopped chives on top, and refrigerate until serving.
All the ingredients can be prepared beforehand, maybe the day before, but it's always better to make the final preparation at late as possible.
Remarks
If you're worried by wasabi, replace it with a dash of Tabasco to keep the spicy taste, or omit it.
If you don't have chives, a parsley or chervil leaf will be ok. It's quite important to have something green with the pink of the mousse.
Raw beetroot taste is a bit disconcerting, if it's your first try don't be surprised by the "earthy" taste. Anyway it's much more interesting than the sweetish taste of cooked beetroot.
