Strawberries are very easy to dehydrate. The preservation technique results in a high quality product, with the strawberries retaining a great deal of both their fragrance and flavour.

Yields and Equivalents
By weight, expect to end up with roughly 1/10th the weight of what you purchased.
1.1 kg (2.4 lbs) as purchased, fresh with hulls = 1 kg (2.2 lbs) fresh, hulled = 110 g (3.8 oz / 2 cups) of dehydrated slices
(Note: Going by Ball’s water loss weight test formula, we would have expected a yield of approximately 280 g instead of 110 g. Admittedly, we are not lab-trained professionals with access to a full lab — that being said, three times our yield was 110 g instead of 280 g. Your mileage may vary. Dec. 2017.)
Here we compare directions from three different sources.
Allow 1 standard square Excalibur drying tray per ½ kg (lb) of sliced strawberries.
