I was particularly struck by this comment:
Initially, KFC meals were built around a whole chicken, with a pick-up surface that contained “an enormous amount of breading, crispiness and brownness on the surface. That makes the chicken look like more and gives it this wonderful oily flavour.” Over time, the company began to realise there was less meat in a chicken nugget compared with a whole chicken, and a greater percentage of fried batter. But the real breakthrough was popcorn chicken. “The smaller the piece of meat, the greater the percentage of fat pick-up,” said the food designer. “Now, we have lots of pieces of a cheaper part of the chicken.” The product has been “optimised on every dimension”, with the fat, sugar and salt combining with the perception of good value virtually to guarantee consumer appeal.
