Have you ever tried a recipe that turned out to go horribly wrong, or maybe the end product, despite being good, just wasn't worth the effort? What was that recipe, and what about it made you say "NEVER AGAIN"?
I ask this as I am actively trying to remove the stench of onions from my Instapot lid's silicone ring after making French Onion Soup in it (so far steaming it with white vinegar on the steam setting, soaking the ring in a water/baking soda bath overnight, and baking it at 250 degrees F for 20 minutes have all done nothing, so I ordered a new one, I give up). And I realized that cutting all the onions and waiting hours for them to caramelize and now this damn smell issue just isn't worth it. Plus I still have frozen soup in the freezer because I can only eat French Onion soup so many days in a row.
FYI, the trick to making caramelized onions is boiling the onions. After you cut up your onions and add them to your pan, add a small amount of water, enough that the water will cook out after a few minutes. The water will steam the onions and cook them more quickly, which will them make them faster and easier to caramelize.
