Raw blue corn contains anthocyanins, the pigments that give its kernels their blue-purple color; yellow corn generally does not contain these same pigments. Both are whole-grain corn, and the overall nutritional difference depends on the variety and how each is prepared.
Raw blue corn kernels have a mild corn flavor with earthy, sometimes slightly nutty notes. Once cooked, they work well in soups, grain bowls, and side dishes; ground blue corn is commonly used for tortillas and other corn-based foods.
Soak dried raw blue corn kernels, then drain and simmer them in fresh water until tender. The time varies with kernel size, dryness, and soaking, so check texture as they cook. Use the cooked kernels in salads, soups, or stews.
Dried raw blue corn is hard and is not usually eaten straight from the bag. Soak and cook the kernels, or grind them into flour; fresh sweet corn is a different form of corn and can be eaten in different ways.
Blue corn masa is traditionally made by cooking and soaking the kernels in an alkaline solution, then washing and grinding them into dough. This process, called nixtamalization, changes the texture and makes niacin in the corn more available to the body.
Blue corn tortillas are made from blue corn that has been ground into masa or suitable flour, not from whole raw kernels. Traditional masa is nixtamalized before grinding; the dough is then shaped into thin rounds and cooked on a hot surface.
Raw blue corn can become less vivid or change shade during cooking. Some of its water-soluble pigments may leach into the cooking water, while the alkaline treatment used for masa can also alter the final color.
Only blue corn varieties suited to popping are likely to make popcorn; most raw blue corn sold as cooking grain is not a popping variety. For reliable results, use kernels specifically sold for popping rather than assuming all blue corn will pop.
Keep raw blue corn in an airtight container in a cool, dry, dark place to protect it from moisture and pests. Refrigerate cooked kernels in a covered container and use them within a few days.
Raw blue corn can be cooked whole for soups, stews, and grain bowls, or ground for blue corn flour and masa. Masa is used for tortillas and other traditional corn foods; whole kernels need soaking and cooking before most recipes.

Raw blue corn refers to uncooked kernels from blue-purple varieties of maize, traditionally grown in parts of the Americas, especially Mexico and the US Southwest. The kernels are usually dried and ground into flour rather than eaten raw; that flour is used in tortillas and other corn-based dishes.
Once cooked, blue corn has a distinct earthy, gently sweet corn flavour and a hearty texture. In Mexico and among communities in the US Southwest, it appears in tortillas, porridges and other everyday foods; elsewhere, blue corn flour can be used in breads or pancakes. It is mainly a source of carbohydrates and fibre, with some magnesium. Pair it with beans or vegetables for a more filling meal, or use it in place of some refined flour in home cooking.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
