"The first case said that the government can’t ban the sales of perfectly safe homemade baked goods. And so, since we already had that victory regarding baked goods, it definitely made things easier the second time around.... People shouldn’t need to buy or rent a commercial kitchen in order to sell fudge or candies...."
Said Justin Pearson of the Institute for Justice, which brought the 2 cases discussed in "Wisconsin residents can sell more than baked goods from home, judge rules" (Wisconsin State Journal).
Pearson asserted "the 49 other states... have better cottage food laws than Wisconsin."
I'd never noticed the expression "cottage food," though of course I know "cottage industry." "Cottage" makes the particular home sound unusually cozy and quaint. If you look back into the history of the word "cottage," you'll see that that originally it meant a small home for a poor laborer. The oldest use of "cottage industry," according to the OED, came from was in the Freeman's Journal (Dublin) in 1849: "Do you wish to make your labourers comfortable? Teach their children the use of the loom, and every kind of cottage industry."
That's "Children On A Path Outside A Thatched Cottage, West Horsley, Surrey" (late 1800s) by Helen Allingham. I found that at the Wikipedia article "Cottagecore." Did you know that some kids today romanticize the cottage and the styles and activities they imagine in and around it?
