Dice mangoes and jalapeno. Yes, I used frozen mangoes. The membrane and seeds are the hot part of the jalapeno, I discarded that. Put into a saucepan, barely cover with apple juice and sugar (about a cup); add orange marmalade. I used a jam that I made from oranges, lemon, and grapefruit from Arizona. (Last March blog, maybe?) Simmer until thick. I used my immersion blender partway through, and chopped it into smaller bits.
