Outside of the kitchen, "crackling" is a scientific term used to describe systems that respond to external pressure through a series of discrete, varied-size "pops". Old School Crackling's!!
To achieve this specific dense and crackling texture, the fat is typically prepared using a slow-rendering method: Crackling Dense Poka
), or a descriptive onomatopoeia for the "popping" sound made during the high-heat flash-fry stage. Outside of the kitchen, "crackling" is a scientific
The rendered pieces are then re-immersed in hot grease (around 375–415°F). This "pops" the skin to create the crackle while maintaining the heavy, meaty center. The rendered pieces are then re-immersed in hot
This is the crispy, browned rind of roast pork or the residue left after rendering animal fat. Unlike a "pork rind," which is just the skin and puffs up light and airy, cracklins include attached fat and meat.
Because cracklins retain extra fat and skin, they do not expand as much as rinds, resulting in a much denser mouthfeel . Traditional "hard" cracklins are particularly dense because they are not fried a second time after rendering, making them extremely firm.
The pork (often back fat or belly) is cooked slowly for 6 to 8 hours to extract grease.
