In dutch they say: "Hunger makes raw beans taste sweet"!
when packing up after windsurfing, they would advise against taking your trapeze off (a huge belly belt that can connect you to the sail, handsfree!) before you had access too food, because more often then not, it would unleash the hunger beast within. It was fun to have that power over your own hunger! GIMME THOSE SWEET BEANS!
It’s a little less used these days. I have German family, they’re all older, so the saying may be out of style compared to their time. It’s usually “best sauce” but I’ve also heard “beste Koch” as well.
