Slice one of the mangoes lengthwise along the seed. Reserve one half (cheek) of this mango, cover and refrigerate.
Take the remaining 1 ½ mangoes and collect the flesh including from around the seed.
Put all of the ingredients (except the reserved mango half) in your blender or stick blender jug and blend thoroughly for 2 minutes or so, ensuring everything is combined well.
Refrigerate for at least two hours until chilled.
Serve with your choice of fruit or nuts
