If you haven't got chutney on hand, this Fiery Onion Relish from "Sundays at Moosewood Restaurant" is simple to make.
1 cup finely chopped onion
4 tsp lemon or lime juice
1/2 tsp Hungarian paprika
1/4- 1/2 tsp cayenne pepper (or to taste)
salt to taste
If you prefer less pungency from the onion, soak it in salted water to cover for about 30 minutes and then drain and rinse it.
Combine all of the ingredients and set them aside for about 30 minutes while the flavours blend.
