Grilled corn on the cob: the perfect summer treat for sweet tooths

Corn on the cob is a beloved summer treat, but have you ever wondered if it’s the same as sweet corn? The answer may surprise you. In this comprehensive guide, we will explore the intriguing relationship between corn on the cob and sweet corn, delving into their similarities, differences, and the science behind their sweetness.

What is Corn on the Cob?

Corn on the cob is simply mature corn that has not been removed from the cob. It consists of rows of kernels, each encased in a protective husk. The kernels are starchy and slightly sweet, with a chewy texture.

What is Sweet Corn?

Sweet corn, on the other hand, is a specific variety of corn that has been bred to have a higher sugar content and a tender texture. The kernels are typically larger, plumper, and sweeter than those of regular corn on the cob.

Is Corn on the Cob Sweet Corn?

The answer is: yes and no.

• Technically, no. Corn on the cob is not always sweet corn. It can be any variety of corn, including field corn, which is used for animal feed or industrial purposes.
• Practically, yes. Most corn on the cob that is sold in supermarkets and farmers’ markets is sweet corn. This is because consumers prefer the sweeter flavor and tender texture.

Why is Sweet Corn Sweet?

The sweetness of sweet corn is due to a genetic mutation that affects the way the plant metabolizes sugar. In regular corn, the sugar is converted into starch as the kernels mature. In sweet corn, this conversion is inhibited, resulting in higher levels of sugar and a sweeter taste.

While they are closely related, corn on the cob and sweet corn have some key differences:

• Sweetness: Sweet corn is significantly sweeter than regular corn on the cob.

Cooking Corn on the Cob

Corn on the cob can be cooked in various ways, including:
