In a skillet, cook almonds in butter or margarine until golden. Stir in brown sugar, orange juice, and lemon juice; cook and stir until sugar dissolves. Add the peaches and cook for 2 minutes over low heat.
Stir in the brandy and cinnamon. Remove from heat.
If you like, in a small saucepan, heat rum until just warm. Ignite with a long-handled match away from flammable surfaces; pour over peach mixture. (This amount of rum won't flame high when ignited.) Serve over ice cream. Makes 4 servings.
