How would Adzuki beans compare to kidney beans.

Chili would be wonderful, but I am one of those heretics that needs the beans.

sure as long as they re compliant and they taste good to you!!
substituting is a way of life with btd!

black eyed peas don't look pretty in a chili but they are good tasting

They are a great tasting, versatile bean.  Out of the bean/legume family, azudki beans have the most balanced protein and carbohydrate ratio.

They are somewhat sweet tasting.  They are used in both savory and sweet bean recipes.  They may sub for kidney beans in recipes if size factor is not a concern, albeit they can get mushy if overcooked and do not hold their shape as well as kidney beans.  

Their taste and flavor is not as prominant tasting as the kidney bean from my recollection, since I have not tasted kidney beans for a long time, since they are an avoid flor blood type A secretors.
