Dried orange rind perks up a lot of recipes, but it's very expensive to buy in a jar. Make your own by grating the rind (not the white part), spreading it out on a dish and placing it the freezer for 2 or 3 weeks.

Save the rind - don't discard the rind of lemon, grapefruit or oranges. It makes excellent flavorings for cakes, frostings and such.
