How to freeze-dry mango

Mango freeze-dries into sweet, crunchy pieces. Ripe but firm fruit slices cleanly and gives the best texture.

Mango is a favorite for snacking because it keeps its tropical flavor and bright color. It is sugary, so like pineapple it needs room on the tray and some patience, but it is less fibrous and usually finishes sooner.

Frozen mango chunks from the warehouse store are an easy shortcut. They are already cut and pre-frozen, which helps sugary fruit dry evenly.

Prep and loading

  1. Pick mangoes that give slightly when pressed but are not mushy.
  2. Cut the cheeks off the seed, score into ⅜ inch cubes or strips, and slice off the skin.
  3. Spread on a lined tray with small gaps between pieces.
  4. If using frozen chunks, cut large chunks in half so they are no thicker than about ½ inch.

How to tell it’s done

  • Pieces snap and are bright orange-yellow throughout.
  • They do not stick together in the bowl.

Not sure? The weight check compares two weighings and the expected dry weight for mango.

Problems and fixes

Large frozen chunks stayed soft inside

Store chunks can be 1 inch thick. Halve them before loading.

Stringy pieces

Some varieties are fibrous near the seed. Use the cheeks for snacking and the flesh near the seed for powder.

Rehydrating and storing

Rehydrate: Eaten dry; soaked pieces get soft and fibrous. By weight, 100 g of dried mango takes back about 471 g of water to return to fresh weight; the rehydration calculator does any amount.

Store: Mylar or jar with an oxygen absorber.

Ways to use it

  • Snacking
  • Powder for lassi and smoothies
  • Trail mix
  • Topping for yogurt bowls

How much fits per batch

At a normal single layer, mango load at roughly 2.3 lb of fresh food per square foot of tray. That works out to:

Harvest Right Small6.9 lb1.21 lb
