What To Know
- If it releases a milky juice and the kernel is soft, the corn is ready.
- A summertime staple, enjoyed with a pat of butter and a sprinkle of salt.
- Hold the cob vertically and use a sharp knife to slice down the length of the cob, removing the kernels.
Summer is synonymous with the sweet, juicy goodness of sweet corn. But how do you know when it’s ready to harvest? The key lies in understanding the telltale signs of ripeness.
The Sweet Spot: Identifying Ripe Sweet Corn
1. Inspect the Husk:
A healthy husk should be tightly wrapped around the cob, with no tears or punctures. Look for a vibrant green color, indicating freshness.
2. Check the Silks:
The silks are the strands that protrude from the tip of the cob. When they turn from pale yellow to a rich brown, it’s a good indication that the corn is mature.
3. Squeeze the Cob:
Gently squeeze the cob through the husk. If it feels firm and plump, it’s likely ready. Avoid cobs that are soft or have kernels that easily detach.
4. Peek Inside:
If possible, carefully peel back the husk slightly to reveal a few kernels. Look for plump, milky kernels with a slight sheen. Avoid cobs with dry or wrinkled kernels.
5. The “Thumb Test“:
Press your thumb against the top of the kernel. If it releases a milky juice and the kernel is soft, the corn is ready.
Optimal Harvesting Time
The ideal time to harvest sweet corn is when the sugars in the kernels are at their peak. This typically occurs between 18 and 21 days after the silks emerge.
Factors Affecting Ripeness
1. Variety:
Different varieties of sweet corn have varying maturity times. Check the seed packet or ask your local nursery for specific recommendations.
2. Temperature:
Sweet corn prefers warm temperatures for optimal growth. Cooler temperatures can slow down ripening.
3. Water:
Adequate watering is crucial for sweet corn development. Drought stress can stunt growth and affect kernel size.
Storage and Preservation
Once harvested, store sweet corn in the refrigerator for up to 5 days. For longer storage, blanch the corn and freeze it for up to 6 months.
