Do blueberries float or sink when washed? Video explains why. Blueberries are particularly effective in muesli, smoothies or tarts.
As blueberries ripen, they produce more sugar and become heavier. Unripe berries, on the other hand, rise to the top. So if you collect all the top berries, you can let them ripen again in the refrigerator and use them at a later date.
