When I was a teenager, I worked at a local place called the Creamy Treat. One of the things we served was foot long hot dogs with chili sauce and onions. I was always elected to chop the onions because I had a method that made it easy to finely chop them.
First, let me say - if there is anyone in your household who wears contact lenses, by default, they should be the onion chopper. When you wear contacts, your eyes don't get all teary! If you don't have anyone who wears contacts, then you should get some of those cool, pink, onion-chopping goggles that Paula Deen wears, LOL!
Step 1: Peel the onion, then make thin, vertical cuts that go almost all the way to the bottom of the onion. But don't cut all the way through!
Step 2: Now turn the onion a quarter-turn to the left or right - now your vertical cuts are horizontal. Carefully hold the onion together, and make thin, vertical cuts almost all the way to the bottom of the onion. Again, don't cut all the way through. These cuts will be perpendicular to the last set of cuts, making tiny "squares"...
Step 3: Cut a small piece off one side of the onion, making that side flat.
Step 4: Turn the onion onto the flat side.
Step 5: Assuming you're right-handed, use your left hand to carefully hold the onion together while you make thin, vertical cuts all the way through the onion.
And that's it! You have finely chopped onions that will flavor whatever you're cooking, but cook down to almost nothing, making them invisible to your family! (My family likes the taste, but gets fussy if they actually see the pieces of onion. Yes, they're all adults. Yes, I know it's weird.)
If you don't need all of the onion right now, just put the extra in a freezer bag and toss it in the freezer for later. You can break off pieces or use the whole bag.
Do you have any tricks for doing something "the easy way"? I live for words like quick, easy, simple, shortcut, shopping, shoes, clothes, makeup...oops, sorry - I got a little distracted!!
