Fruit
Ripe mango (peeled, stoned, sieved)
With care — Allowed by some hospitals and not others, or allowed only prepared a particular way.

How to prepare it
Use it fully ripe. Peel it, cut the flesh from the stone, then blend it and push it through a sieve to remove any fibres.
Where hospitals differ
The leaflet this book follows does not name mango. It is treated as a peeled, deseeded, sieved fruit.
