the.com/deep fryer

A vat that turns regret into flavor, three hundred and fifty degrees at a time.

means An appliance that cooks food by fully submerging it in hot oil, usually between 325 and 375°F.

from 'Deep' here is simple and old, describing full submersion rather than a shallow pan-fry; 'fry' traces back through Old French 'frire' to Latin 'frigere,' meaning to roast or fry. The compound itself is a plain, functional 20th-century coinage — household deep fryers followed industrial and restaurant versions, naming the device exactly for what it does: fry things deep in oil, no poetry required.
