Why doesn’t this exist?
Take dried beans, roast 'em, grind 'em, and brew some bean juice?
I have no idea if it would taste good or not, but we don’t know if we don’t try.
Edit: I need to see what dried beans I have and maybe go shopping. I will give this a try with a couple different types of beans and report back if I fart or not.
Hope you have some alpha-galactosidase at your disposal.
The simplified explanation: A reason beans give some people gas is due to certain types of sugars and carbohydrates they contain. Those sugars are water soluble. Seems like brewing beans would concentrate those sugars and lead to epic tootage.
Also, one method for reducing how much gas that beans cause is to soak them in lots of water. Basically, soak them for up to 8 hours, drain, rinse, and repeat a couple more times. It works on the same principal, that the soaking process will remove at least some of the problematic, water soluble sugars. Supposedly adding a small amount of baking soda helps, too. I’m less certain about that.
I think Alton discusses this on Good Eats, and a long soak doesn’t really make a difference (according to him).
He did have a solution, I just don’t recall. May have been baking soda.
Oh, if Alton said that then it must be true. Who’s Alton?
I told you, Good Eats. I wasn’t ambiguous. And he gives chemistry reasons why.
He has a food chemist that explains things.
So stick it where the sun doesn’t shine.
