Berries should be stored in the refrigerator and will keep
for several days depending on the variety and/or the weather and humidity.
If you wish to rinse before using, do so right before you are ready to use them. Rinse berries by floating them in water then gently transfer
to a colander or paper towels to remove moisture.
De-stem your berries after rinsing and they will stay firmer (with the exception of raspberries, which naturally lose their stem when picked).
Berries can be frozen in a single layer on a cookie sheet
then packed in freezer bags or containers once firm enough to handle.
