This is the laziest, most brilliant trick ever. Grab a potato masher or a sturdy fork. Mash some beans right in the pot.
Smash about a quarter of them. Watch the liquid turn creamy and cloudy. The bean starch releases and magic happens.
Fun fact: Ancient Romans did this. They didn’t have blenders, so they used their fists. Well, maybe not fists, but you get the vibe.
