Random fact: The scent of burnt buns has a very long life cycle.

I burned burger buns that I set to warm on the toaster nore than two and a half hours ago. The scent is still going strong. I opened the windows (only for a while because it's really cold out there). I set the kitchen extractor fan. It endures. The burn persists.

I'm sure this is parable-worthy.

@AmaryllisLanza simmer a cup of white vinegar mixed with a cup of water.

@annamousse I should have known! Have you seen my previous thread on vinegar? Vinegar is always the answer. Thank you. I'm going to do that now.
