Syrup:
½ cup (1 stick) butter
½ cup sugar
¼ cup pineapple juice concentrate (right out of the can)

I took the easy way by making buttermilk pancakes from a store-bought mix. Just add coarsely chopped macadamia nuts to the batter, as much as you'd like.
For the syrup, in a small saucepan, place butter, sugar and pineapple juice. Heat over low heat, stirring, until butter melts. Do not boil.
I have to have pancakes with Canadian bacon, but sausage or ham will do just fine, too.
