Violence by oil: seconds of heat, maximum crunch, zero time to overthink it.

means To cook small or thin pieces of food very quickly in intensely hot oil, so the outside sears and crisps before the inside has time to overcook.

from 'Flash' has meant 'instantaneous, sudden burst' since around the 1800s, borrowed from the quick blaze of flame or light it names — think 'flash of lightning' or a photographer's flash. 'Fry' is far older, tracing back through French 'frire' to Latin 'frigere,' meaning to roast or fry. Put together, 'flash fry' is a 20th-century kitchen compound describing exactly what it says: frying so fast it's over in a flash.
