New to me, anyway. This will soon be turning up in jams and pepper sauces, eventually in cereal bars and smoothies. It has six times the vitamin C as oranges, twice as much calcium as milk and loads of antioxidants, B vitamins and minerals. It's also rich in pectin making it pretty darn useful as well as a vital income source for women in Malawi.
It's flavor is described as somewhere between grapefruit, pear and vanilla.
Remember, you heard it hear first (well not quite). Yes, I still read Nat Geo).
