Sweetcorn is ready to pick when the silks (the strands at the end of the cob) are completely brown, dried out, and brittle. Additionally, you can check ripeness by peeling back part of the husk and piercing a kernel; if a milky white juice comes out, the corn is ripe. At this stage, the ear will feel soft to the touch, and the tip will be more blunt instead of pointed. It is important to harvest sweetcorn at this precise moment to enjoy maximum sweetness and tenderness before the kernels become too hard or mealy.
