   1      small         onion
   1      piece         fresh ginger -- 1 cm
     1/2  tablespoon    olive oil
 150      milliliter    fish stock
  60      milliliters   dry sherry
                        salt to taste
                        cayenne to taste
   1      large         avocado
     1/2                lemon -- juice only
 300      gram          crabmeat
                        cooked pasta for four

Preparation:

If you don't want the trouble of dismantling crabs to obtain the crab meat, use frozen meat. Canned crab meat is very poor by comparison. And if you haven't time to make fish stock, chicken stock can be substituted at a pinch, though the result won't be quite as good. Boil a large pot of water and cook enough pasta of your choice for 4. Meanwhile, chop a small onion, grate a centimeter or so of fresh ginger and simmer them gently in 1/2 tablespoon olive oil until soft. Add 150 mL fish stock and 60 mL good quality dry sherry plus salt and cayenne pepper to taste. Mash or process together the flesh of 1 large avocado and the juice of half a lemon. Add the avocado to the fish stock together with 300 g of crab meat, and stir well, leaving the sauce on the heat just long enough to heat through. Taste and adjust the seasoning. and add more lemon juice if necessary. Serve over the hot pasta. From an article by Meryl Constance in The Sydney Morning Herald, 7/13/
