Introduction to Freeze Dried Strawberries
Strawberries are having a cultural moment. They might not be the usual ingredient on every red-hot trend list, but freeze-dried strawberries are suddenly popping up in cooking and baking, from all parts of the foodie and food-blogging universe. Their intense flavour, not-too-sweet taste and long shelf-life mean they're a lovely ingredient to add to lots of different dishes – and they open the door to some cool new things you can make at home.
What are Freeze Dried Strawberries?
A teeny, almost inconceivably minuscule amount. Often, the lyophilisation process starts with heating the fruit stock to kill microbes, but, in the case of hot berries, that step is skipped. Instead, the frozen fruit is freeze dried. The basic strategy is to chill a food to a low enough temperature that its moisture doesn't vaporise but instead freezes. The surrounding air is then reduced to a fraction of its usual atmospheric pressure – around 1 per cent of a millibar. Given a vacuum where frozen water doesn't expand, the frozen water in that strawberry can evaporate directly from the solid to the gas phase, jumping past the liquid phase. The strawberry that results is almost the same as the original when it comes to nutrients. It weighs less than 2 per cent as much as before. It takes up less space than before. It's still a strawberry.
