Sweet mangoes from Hawaii spiked with hot chilies produce a jam with a kick. "I love the combination of hot and sweet," says Theresa Liu. She likes the jam with poultry or fish or mixed with cream cheese and served with crackers. If you don't want to can the jam, let it cool and spoon into containers. Cover and chill up to 3 weeks. To store longer, leave about 1 inch headspace in containers, cover airtight, and freeze.
