Whenever I have extra apples, mangoes, pineapples or strawberries, I normally cook them down and serve them over pancakes or french toast, or with ice-cream. They make for the most delicious topping possible and are incredibly easy to prepare.
In a pan, melt the butter, then add the sugar, cinnamon and water. Bring the mixture to a boil and allow it to simmer gently until it begins to thicken. Then add the chopped fruits and salt, stir to coat them with the sauce. Cook over medium heat for about 5-10 minutes until the fruits are tender, make sure to stir occasionally and add more water if needed. The sauce will thicken as it cools but if you want it extra thick, add half a tsp of cornflour mixed in a bit of water. Taste and adjust for sweetness if need be. Once done to your liking, turn off the heat and allow the stewed fruits to cool. Serve over pancakes, icecream, french toast etc.
