Berries (as with any produce) can be pretty dirty! We recommend washing your berries really well with a vinegar and water mixture (1 part vinegar to 3 parts water). Simply add the vinegar and water to a large bowl, dump the berries in, and use your hands to gently agitate the berries, allowing any dirt or grime to release. Let the berries sit for at least 5 minutes in the vinegar and water mixture, then drain them in a colander and give them a good rinse.
