For bread doughs, I used to think doing it by hand was superior to using the hook attachment in the stand mixer. Not sure why, and wasn’t snobby about it, but I guess just because I started making bread years before I got the stand mixer. Now I pretty routinely use the mixer for bread and pizza doughs, except maybe challah (and not sure why I’ve stuck to counter kneading for that one??). Daughter #2’s college is close enough she can come home weekends if she isn’t running around with friends and whenever she comes home, she makes bagels for the week using the stand mixer for kneading and resting steps for the dough. She’s probably never kneaded dough by hand.
I’ve only made meringue once with a balloon whisk and actually broke a wire on the thing I was threshing the stuff so hard (and it was my favorite whisk!). Not the best environment - was renting a house on Islamorada in the Keys and it was damned humid. But the rental didn’t have a mixer or beaters or anything. It worked out - see my profile pic (it’s Key Lime pie with meringue - for some reason everyone wants to put whipped cream on it but that’s just wrong!). Normally meringues are with electric beater, sometimes the stand mixer whisk if it was already out for something else.
Slicing taters, and other veggies, I now really like the mandoline. There was a thread on mandolines recently where I mentioned having had a bad (cheap) one to start with but once I got a decent one gave up the knife when it comes to slicing veggies, unless I only need, e.g., one tomato.
For some reason I find cleaning the food processor to be pure drudgery, so I still grate potatoes or anything else needing grating on the box grater despite the FP’s grater & slicer attachments doing a fair job of it. I pretty much only use the FP for making butter nowadays. Oh, hummus too.
Like Lectroid said, I only use the immersion blender to make mayo. That’s the first way I learned. I’ve seen other methods and tried one (regular blender) just once, but the IB is just so darned easy. Start at the bottom, hit the power, draw it up, and presto! Done in 4-5 seconds. Can’t imagine trying to whip it up using a balloon. How long’s it take?
Edit - any recipe calling for minced garlic, ginger, turmeric, lemon grass, etc., I use the microplane grater instead. Is that wrong?
