How to pick like a pro

Is it ripe?
Strawberries are ready when fully red to the stem. Blueberries should be deep blue with no red at the stem end; ripe ones roll off into your palm. Blackberries are ripe when dull black, not shiny.
How to pick
Pinch strawberries off with a bit of stem so they keep longer. Cup blueberry clusters and roll with your thumb. Pick into shallow containers so the bottom layer is not crushed.
Best time to go
Early morning, before the heat softens fruit and picked-over rows fill up.
Keep it fresh
Do not wash until you eat them. Refrigerate in a single layer; most berries keep 2 to 5 days.
