Corn on the cob was 6 for $.96 at my local Safeway this week. A summer side dish doesn't get much cheaper than that!
Here's a tip from the Food Network to kick your corn up a notch:
Peel back the husks from the corn and remove the silk. Butter the kernels and sprinkle with salt and smoked paprika. Fold the husks back over the corn and grill over low heat until cooked through, turning occasionally, 12 to 15 minutes.
