Blue popcorn is a unique variety of popcorn that has blue kernels. When popped, these kernels produce fluffy, white popcorn with a slightly nutty flavor. The blue color comes from the presence of anthocyanins, which are natural pigments found in many blue and purple foods. This type of popcorn is often grown in the United States, particularly in regions like Indiana and Ohio. It is popular among gourmet popcorn enthusiasts and can be used in various recipes or enjoyed plain. Blue popcorn is also considered a healthier option due to its whole grain content and lower glycemic index compared to traditional yellow popcorn.
