I'll assume you know about oats and there's unprocessed, slow cook, quick cook, instant... The problem with quinoa is its all marketed as quinoa although by analogy, you can buy completely unprocessed which takes forever, somewhat processed which still needs some rinsing, and super processed safe to use in prepared box mixes. You have to read the fine print. If you make the mistake of treating raw unprocessed from a farmers market as if it were perfectly dehulled ready to use box mix grade, it'll taste so awful and bitter that you'll spit it out, and probably swear off the product.
Maybe a worse analogy is its like getting a live chicken, vs a shrink wrap boneless skinless tray at the supermarket, vs getting mcnuggets at the drive thru, its all marketed as "chicken" but it matters a lot what kind you buy.
There's probably a startup lesson in here. Life would be a lot more consistent if the quinoa guys never sold processed, for example. It might be less convenient but at least it would be consistent, and inconsistency means confused unhappy users. Consistently PITA sells better than inconsistently PITA.
