Because National Bean Day on January 6 falls in the middle of winter, it’s the perfect excuse to cook favorite comfort food. Wondering why National Bean Day is held on January 6? That’s the same day as the famous geneticist, Gregor Mendel, died in 1884. Mendel used bean plants and pea plants to develop theories on genetics in plants. So the formation of National Bean Day has more to do with scientific development than how good bean recipes taste. But don’t let that deter you from enjoying eating beans on this holiday!
