There is rocket science involved here. Ok, I exaggerate but it is true that a special device (on loan from the Japanese inventor) is the “secret weapon” placed in the deep fryer to change things at a molecular level. I was told that basically, it forces the oil to NOT remain in the batter during the cooking process. So the end result is extra crunchy fried chicken. Or in other words, “kakakaraage” (yup, I invented an onomatopoeia 🤓😜).
