Try slow cooking rancid beefribs for 3 days susevide then putting a rack in an air fryer to see if it ‘might mask the stench.’ Our neighbors were dry heaving. House smelled worse than a civil war hospital for weeks.

Also try burning the crap out of mole sauce for like 3 hours.

Rotting onions compare.

It smells like a partially decomposed corpse. I don’t know what a corpse smells like, but I believe them. It’s awful.
