Preserving Summer Fruit in the Freezer
Flash-freezing is the only way to keep summer fruit from turning into a solid, unusable block of ice. By spreading pieces in a single layer on a tray until they are firm before moving them to a bag, you retain individual texture and ensure they pour out like loose marbles when you need them.
Ripeness is the clock
Freeze fruit at its peak. Cold temperatures preserve flavor, but they do not improve quality; if it is mealy or bland before it enters the freezer, it will stay that way.

Separate to preserve structure
The goal is to harden the exterior of the fruit before it has a chance to fuse with its neighbors. A thin layer of frost on individual pieces is better than a solid brick.
The method.
Wash and dry
Rinse fruit thoroughly and pat completely dry with a tea towel. Excess water creates large ice crystals that ruin the cell structure of the fruit.
Prep the pieces
Hull strawberries, pit cherries, and slice larger fruits like peaches or nectarines into uniform wedges. If using stone fruit, toss slices in a teaspoon of lemon juice to prevent browning.
Arrange
Line your baking sheet with parchment paper. Spread the fruit in a single layer, ensuring no two pieces are touching.
The deep freeze
Place the tray flat in the coldest part of your freezer. Leave it undisturbed for at least three to four hours until the fruit is hard to the touch.
Store
Transfer the frozen pieces into freezer bags. Press as much air out as possible before sealing to prevent freezer burn.
When it doesn't go to plan.
Label bags with the date and the type of fruit to avoid guessing later.
Small berries like blueberries or raspberries do not need to be sliced, but always check for stems.
If your freezer has a 'quick freeze' setting, turn it on an hour before you slide the tray in.

Do I need to add sugar?
No. Sugar helps with syrup-based preservation but is not necessary for dry freezing individual pieces.
How long will they last?
They are best used within six months. Beyond that, the lack of humidity in the freezer begins to draw moisture out of the fruit.
