I love this way of eating mangoes. Many of the mangoes available now are not quite ripe, so this is a good way to eat them. The tartness of the mango is extra zingy with the salty/spicy dip. Mexicans do something similar to this too. The dip also tastes good with watermelon, pineapple, ripe mango, or cantaloupe.
Slice and peel 2 green mangoes.
Dip in a mixture of:
2 t salt
1/2 t cayenne pepper
1/2 t sugar
