This fruit of Mammea americana is what I was advised to sample as well. The tree grows in the tropics and the fruit is delicious.
What interests me most about the Mammee is that the unripe fruits are rich in pectin. So I am looking forward to concocting some delicious jams with this fruit. It also lends itself to great tasting pies and tarts.
Recipes will be posted in due course of time.
