pamsy & Rinshin, These are good ideas I'm going to try. I especially like the Japanese baked avocado recipe as I've never baked an avocado or eaten it with miso or soy sauce, so I’ll try it.
Pamsy, it's interesting to hear that avocados are hard to come by in the UK. When I went to my Wegman's in northern Virginia today, the bin was nearly overflowing with avocados- some ripe and some unripe. They (Haas) have Mexico stickers on them this time of year.
