GRAPEFRUIT FISH
When we lived in Oregon we ate a lot of red snapper, which was a very inexpensive fish that can be fixed innumerable ways.   And when pink grapefruit were ridiculously low in price I tried them in everything.  So naturally they ended up together.
 
1 lb. red snapper or other mild white fish
1 pink grapefruit
2 Japanese hot peppers (with seeds)
1 small clove garlic
4 slices fresh ginger
1/4 cup vinegar
1/2 cup sugar
1 1/2 Tbs. cornstarch
1 Tbs. sesame seeds
10 drops red food coloring (optional)
2 1/2 cups water (or 2 cups water + 1/2 cup wine)
Rice
 
Begin cooking rice according to package instructions
Chop peppers, garlic and ginger very fine.  Put vinegar, sugar and cornstarch in a 2 quart saucepan.  Add 2 cups water slowly, stirring to prevent lumps.  Add the  chopped spices, bring to a boil and cook 1 minute.  Remove pan from heat and set aside.  Remove any bones from the fish, and cut fish into 1" square pieces.  Cut grapefruit sections into 1" pieces and set aside.  Put fish in a clean saucepan, add 1/2 cup water or wine.  Add more water if necessary to cover fish.  Boil fish until it just turns white and drain.  Add the cooked fish, sesame seeds and grapefruit to the sauce, bring to a boil and serve immediately over rice.
