1.5 cups water
1.5 cups sugar
1 bag cranberries (12 oz.), washed, all soft ones discarded
grated rind of 1 orange (optional)
Mix water and sugar together in a saucepan. Bring to a boil, making sure the sugar is dissolved. Add the cranberries, bring to a boil again, and continue boiling till all the berries have popped, about 5 minutes. (The recipe says you should skim any foam, but I find this hard to do, and it doesn't taste any different with the foam, so forget it.)
Add the orange rind, if desired.
