Corn chips are a food I've never known anyone to make from scratch, yet so many recipes use corn chips as ingredients. Still, if you wanted to, you could make your own corn chips. As an ingredient, corn chips are crushed and used as breading, sprinkled on top of soup, or used to dip into chili and cheese.
Corn chips also seem to be synonymous with home sports-viewing parties. I'm not sure why, but every sports party I've been to has had corn chips.
Hrm...maybe that's what today is Corn Chip day - it's close to the Super Bowl! Today would be the day to buy some corn chips for your Super Bowl Party!
