Normal or High Sugar (su) corn gives you heart corn flavor, a firm feel, and creamy texture. The "SU" designation stands for "sugary-1," which refers to the genetic trait that affects the sweetness and texture of the corn. SU corn varieties have a higher sugar content compared to other types of corn, such as standard field corn or dent corn, but lower than new, extra-sweet varieties. In short, SU corn is the classic sweet corn you grew up with. It is commonly grown and appreciated for its sweet and juicy kernels, making it a popular choice for fresh consumption and use in your favorite dishes.
