Now you have to clean the food processor. Which is enough of a trouble to prevent me from using it very frequently.

Remove from the motor/base, separate parts, spray with water and toss in the dishwasher. And wouldn't you have to clean the cutting board and knife anyway?

The most important part: much less eye watering.

> Remove from the motor/base, separate parts, spray with water

And then do in reverse once it's clean. And you're wondering why it seems like too much trouble...?

Plus you still need the knife and cutting board anyways to chop off the ends of the onion before peeling it. So it's not even instead of, it's in addition to.

Much less time to dice it yourself for one or two onions. Ten or twenty onions, OK it's food processor time.

Reassembling a food processor takes mere seconds.

Overall, doing all this is much more convenient than manually chopping onions. It's not even close. This is one of the ideal use cases for a food processor.

Maybe you're really slow at chopping onions? It takes like 15 seconds to dice an onion once it's peeled. Taking out, disassembling, rinsing, racking, unracking, reassembling, and putting away a food processor takes much much longer, any way you slice it. You're right, it's not even close -- manual dicing is always going to win for just a couple onions, unless you're already using the food processor for something else.

Maybe you're a masochist and like the sulfuric acid in your eyes?

Let it spit in your eye, for it is doomed. Soon you will consume its essence and that is Good.

Or maybe it's not a big deal for just a couple of onions?

If it's really bothering you, make sure your knife is sharp enough. A dull knife makes dicing much slower and releases many, many more compounds.

That works for the housing, but not for the blade which usually gets food jammed up in every little crevasse. You can't stick those in the dishwasher because it'll dull the cutting edges. Washing the knife and board is trivial by comparison.

But I don't really have trouble with my eyes with onions, that may be the deciding factor.

> You can't stick those in the dishwasher

I stick my food processor blades in the dishwasher all the time; never hurt them any.

Well too be fair they usually come pretty dull from the factory already.

Of course you can stick the blade in the dishwasher. It works fine. What do think the dishwasher is doing, sandblasting?

Throw your knives in the dishwasher and they’ll dull right quick.

Food processor blades are usually stainless steel, which is a lot less sensitive to the dishwasher.

And food processor blades are driven much harder than hand knives, so they don't have to be as sharp.

Some substances in the dishwasher detergent are bad for steel, like sodium silicate.

Agreed. Food processors only make sense for larger amounts of processed foods. I'm glad to have one for those occasions though.

Nice if you want onion mush.

A few quick pulses doesn't make mush and is fine for a lot of applications. Otherwise, food processors have dicing kits https://i.imgur.com/cXbZ9aC.png

I enjoy the art of prep with my beautiful wa gyuto, I truly do. But if you put a 5 pound bag of large onion on front of me to dice, I will prefer the machine...

Yes, there is an inconvenience threshold that must be reached before bringing out the food processor. We also have a mandolin that can make cross-cuts for intermediate jobs: https://a.co/d/da8OxnE

That's a really cool mandoline, thanks for sharing. Not only is it safer but it's accessible for folks with motor issues. I'm still using a cut resistant glove and ignoring my plastic guard on a standard one.

The metric being optimized here is uniformity of cut.
