/ck/ - Food & Cooking

Hey /ck/, /a/non here to ask a question.
So today my girlfriend went to the store to hit up grocery sales, and tonight she was gonna make spaghetti (my favorite!). She forgot something at the store so I went really quick to pick it up for her, and when I come back to the apartment, holy shit my eyes are being assaulted with burning and pain.

Apparently she got brown onions (pic related), as opposed to white onions like she usually uses. Is there a reason these things are letting out eye burning fumes throughout the apartment? I'm literally sitting on the doorstep with the door open because of how much this is making me tear up and burn.

I ask you, /ck/, is this worth it? I really hope these are some really, really good onions. I also really hope this isn't normal and that this batch of onions is bad or something so that we won't have to go through this suffering the next time she cooks something with those onions.
