Thanks everyone for all the suggestions. I've taken them, weighed them up with my sanity and ability to turn things out of my kitchen at a decent clip, and have come up with the following meny. Any final thoughts/suggestions/warnings you may have are appreciated...
Drinks & nibbles: lychee martinis (made a few this weekend, and found them pleasant but lethal - they're best when on-the-edge-of-freezing), strange-flavour peanuts (already made, and probably the best batch I've managed so far), mochi with sesame stuffing (I'll be sure to warn people about the choking issues...)
Cold dishes: (all to be prepped earlier in the day, except for the beef which can be done tomorrow)
Long beans with fresh ginger sauce
Red peppers with sweet & sour vinegar
Beef with tangerine peel and chilies
Steamed whole fish, Sichuan style
Red-braised belly pork (to be done Friday and reheated on the day)
Whatever-greens-I-happen-to-find-on-the-day stir-fried with garlic
Long egg noodles with sea flavours
Candied kumquats, sesame candies, candied soursop
This should leave me with only two last-minute stir-fry dishes, although the final prep for the fish and steaming will take around 10 minutes as well.
Well? I've done all of these dishes before and have done a similar-ish large menu on one occasion, so know that the steaming/braising/cold dishes combo will make it manageable. Any last words of advice before I go in?
