Drying blueberries in the oven is a simple and effective method. Explain How?

The following are the processes that must be followed to successfully dry your blueberries: 

  • If you’re using a steamer insert, fill a medium-sized pot halfway with water and place the steamer basket on top.
  • Bring the liquid up to a rolling boil, stirring constantly. Bring the water to a boil as soon as the blueberries are added to the pot, stirring constantly.
  • After withdrawing the steamer basket from the hot water, run it under a cold water tap to cool it down. This will prevent the berries from becoming overcooked and will help to keep them fresh. This procedure is necessary to allow the blueberries’ outer skins to open up and become edible.
  • Allow the blueberries to lie on the paper towels for 10 to 20 minutes before using.
  • When baking the blueberries, it is best to use several baking sheets. The trays will be stacked together in the oven to form a single layer. To begin with, one to two kilos of blueberries each tray is a reasonable amount to start with.
  • In your oven, each baking sheet should have a one-inch gap between it and the next.
  • The oven should be preheated at 140 degrees Fahrenheit. For the blueberries to bake properly, one of the oven doors should be left open. A gas oven door should be one to two inches thick, whereas an electric oven door should be four to six inches thick, depending on the model.
  • While the blueberries are drying in the oven, rotate the baking sheet and gently stir the blueberries with a spatula every 30 minutes to ensure even drying.
  • Place the cooling racks under the baking sheets and let them cool completely before removing them. Once the blueberries have cooled to room temperature, place them in airtight containers and store them in the refrigerator.
