While researching a way to minimize mold on berries, I came across an article by Harold McGee which suggested doing something completely counterintuitive: Rinsing them in hot water for 30 seconds. He did research and found that swishing strawberries, raspberries, and blackberries in 125 degree water for 30 seconds significantly reduced the development of mold without reducing the quality of the fruit. He suggests 140 degree water for 30 seconds on blueberries which have thicker skin.
I have tried this on strawberries and found it to be effective. I used a candy thermometer to check the temperature of the water. I will have to wait until the rest of my berries ripen before I can do more experimenting.
Do you have any tips for reducing fruit spoilage?
