Preparation

Cut in half or in 1.25cm slices, as the row prints. It gives the two as alternatives, so no one thickness is held.

How to tell it is done

  • Still red rather than brown
  • Snaps or tears cleanly rather than bending
  • No cool, damp patch in the middle of a slice when it is torn

Specific to this model
Why this rating
A published dehydrating row from the manufacturer's own Quick Start Guide for this machine, under a block headed fresh. The chart has no amount column, so the slice a row prints is the only measure it gives.

What this does not cover

  • Published by the manufacturer for this model. It is evidence about this appliance and is not general advice.
  • This machine has two drawers. The chart prints one amount for the row and does not say which drawer it is for, or whether it is for one drawer or both.
  • The chart heads this block Fresh Fruits & Vegetables, and the row is held as fresh on that heading. The word is the block's and not the row's own.
  • No quantity is stated. The dehydrate chart has no amount column, and this row prints no one slice thickness either.

    Retrieved from a retailer's document store, Euronics, which mirrors the manufacturer's booklet. Argos's manual library holds an earlier revision of the same guide, 200515_Mv1, which differs in a few printed amounts; the later revision is the one held here.

Chilled

Cooked as fresh: use the fresh figures above. Raw food sold chilled is the fresh state under another name, and the charts those figures come from start from fridge-cold.

Manufacturer figures with no state given

This is a published figure for one named machine. The manufacturer does not say whether this is fresh or frozen. So it is kept apart from the figures above, and not used as the answer for any of them.

  • Ninja Foodi MAX Health Grill & Air Fryer AG551UK: 60°C for 360–480 min

    Published range of six to eight hours for strawberries cut in half or in 1.25cm slices. The chart prints no amount.

What usually goes wrong

Brown instead of red. Strawberry pigments break down with heat, so a batch dried above the published temperature loses the colour that is half the point.

Running the appliance safely

The rules for the machine are the same whatever is in it: plug it straight into a wall socket, leave clear space round it, do not overfill it, do not leave it running unattended, and unplug it at black smoke or an electrical smell. They are set out once, each with its source and what to do if it has already happened, and not repeated on every food. Every rule for running an air fryer safely.

Strawberries in fast-moving hot air

A strawberry is around ninety per cent water in a very soft structure, so the mass loss during dehydrating is enormous and the slices shrink to a fraction of their size. What is left behind is concentrated sugar and acid, which is why dried strawberry tastes so much stronger than fresh. The low temperature matters more here than for most fruit: the colour pigments break down with heat, and a strawberry dried too hot goes brown instead of red.
