Remove husks and silks from corn. Cook corn in boiling water to cover 10 minutes; drain.
While corn cooks, combine margarine, curry powder, red pepper, and mint, if desired, in a small bowl. Brush margarine mixture evenly on corn. Serve immediately.
To check the sweetness of fresh corn, pop a kernel with your fingernail. The corn will taste sweet if the liquid from the kernel is milky white.
