Did the hardness test extend to your coworker's head?

Love that 'simple tech with big impact' line. We did the same thing last year. Make sure you check the learning schedule after a few weeks, ours tried to turn off the heat at 3 PM on a Tuesday because it thought we left early once. Also, if you have any rooms that get more sun, you might need to tweak the settings. And tell your team to stop manually adjusting it, that messes up the learning.

But what if the issue wasn't that from-scratch recipes are too hard for groups? I mean, salt mistakes can happen to anyone, right? Maybe next time you could measure the salt into a small bowl first before adding it, so you don't lose track. I've seen people use little cups for each part to avoid mix-ups. With a bit of practice, those fancy cookies might turn out great even for a crowd. It's all about getting the steps down, not just picking easy stuff.
