What are the other main things that cause shaky hands, from what you've seen @the_cameron? I've noticed stress and too much caffeine can do it for me. Figuring out the root cause makes it easier to fix.

Always amazes me how many things pull double duty.

Actually, I didn't mention shutting out family wisdom, but I get why you're asking. The carb trick wren958 talked about shows simple mechanical know-how. That hands-on thinking still exists, but scanners make it easy to skip the old ways.

That math never really checked out for me. Dried stuff lasts forever in the pantry, so you can buy huge bags on sale. A box of penne stretches further because it soaks up sauce better. That fresh pasta often needs a rich cream or butter sauce just to work, which adds cost right back. The time saving is real, but the cost per meal feels higher.

How long did it take to get that good freehand? I'd probably make a huge mess trying it.
