Why is the sound of crispy food, such as chicken skin, roasted pork belly, chips, etc., appealing and mouthwatering?

Ever hear of Pavlov’s dog?
A scientist noticed the dogs in his experiments on digestion were salivating when the attendants arrived whether or not they had food. He considered that it may have been a conditioned response, and ‘trained’ them to salivate on the sound of a metronome.
Essentially the brain connotes any neutral stimulus – white labcoat, metronome, sound of sizzling – with food if it’s commonly accompanied by food. The sizzling is your brain telling you “This is a situation where you can get food!” and kickstarting the physiological process of digestion – salivation, or suddenly increased appetite.
