So, what are kitniyot, anyway? Well, it's a Hebrew word that refers to foods like legumes, corn, and rice. These foods were originally considered non-kosher for Passover by some Jewish communities, but over time, the rules have relaxed a bit. Today, some people still avoid kitniyot during Passover, while others don't.
If you're wondering why corn is considered a kitniyot, it's because of its historical association with grains. In the past, corn was often ground into a flour and used to make bread, which is a big no-no during Passover. Even though corn isn't technically a grain, it's still tinged with grain-like behavior, which makes it a kitniyot.
