Look for plump, shiny, deep-coloured berries that don’t have the hull attached. If the hulls are attached, it’s a sign that the blackberries were picked too early and they will be very sour. Avoiding buying berries with dents, bruises or mould.
As with all berries, it’s best to use blackberries soon after purchasing them. However, they can be kept in the fridge for a couple of days. Simply lay unwashed berries in a single layer on paper towel. It’s important not to wash the berries before refrigerating, as this can cause them to deteriorate quickly.
To Freeze Blackberries rinse under a slow stream of cool water (to avoid damaging the berry), and then allow to dry completely. Place the berries in a single layer on a sheet pan lined with parchment paper. Freeze until firm., then place the berries into a freezer-safe plastic bag and remove excess air. Frozen blackberries can last up to 8 months in the freezer.
Rinse blackberries gently under cool water before using. Pat dry and enjoy as-is, or add to your favourite recipe.
