Is it spelled chile or chili?

Is it spelled chile or chili? It is NOT a regional thing!

There is indeed a difference between chile powder and chili powder, and: 

Once you know what the spelling means,

you will know what it is and what is in it! 

 CHILE:  Spelled with an"e" at the end, refers to the fresh or dried plant or pod or fruit of any member of the pepper family.

CHILI:  Spelled with an "i" at the end, refers to soups, stews and/or sauces made with fresh or dried chile peppers (like chili con carne).

CHILE POWDER:  When spelled with and "e" at the end, means it is a powder made from one or more dried chiles exclusively.  This is sometimes referred to or marketed as POWDERED CHILES, or CHILE BLEND (if it contains more than one kind of chile powder).

CHILI POWDER:  When spelled with an "i" at the end means it is a mixture of ground, dried spices (for example:  cumin, garlic, onion) and chile powder, meaning:  the manufacturer has added spices to the chile powder or a blend of chile powders.
