Sifting flour. Sautéing spices “to release the flavor” and then adding them to stew where they’ll simmer for an hour or more. Pretending “restaurant quality” is anything besides twice as much butter and salt as you’d dare use at home. “One tablespoon of olive oil” to brown absurd amounts of meat at high heat. Once you start recognizing recipe BS, you see it everywhere.
Spices in a stew will only ever possibly reach 212. When blasted on dry heat they can get higher. The tablespoon of olive oil is to kickstart the process, after that enough fat will render out of the meat to keep it going.
Blast them on high heat and you drive off most of them, and polymerize the rest to creosotes.
