Corn varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common corn varieties compare.

VarietyBest for
Yellow SweetEveryday grilling, boiling, and corn salads: firm kernels and a classic sweet flavour that holds up well to heat.
White SweetRaw salads and lighter side dishes: sweeter and more tender than yellow, with a delicate flavour.
Bi-ColorAn all-round option for any cooking method: a mix of yellow and white kernels in one cob.
Baby CornStir-fries, noodle dishes, and Asian-style cooking: eaten whole, cob included, with a mild crunch.

Which should I pick?

For everyday grilling, boiling, and summer salads, Yellow Sweet is the standard choice: widely available, reliably sweet, and sturdy enough for the BBQ. White Sweet delivers a sweeter, more tender bite and suits raw eating and lighter salads. Bi-Color (Sugar and Butter) is the all-purpose pick when you want both in one cob. Baby Corn suits stir-fries and Asian dishes where the whole small cob goes in.
