- In a heavy saucepan, combine the onion, honey, vinegar, pineapple, curry powder, ginger, salt, and red pepper flakes and mix well. Put the pan on the stovetop and cook over high heat until the mixture comes to a full rolling boil, stirring frequently. Reduce the heat to low and cook the chutney, stirring occasionally,until the pineapple is tender and the mixture is thickened, about 20 to 30 minutes. Take the pan off the heat and cool the chutney completely. Then stir well. And store.
