Beef tastes good. It’s as simple as that. One reason is the presence of glutamates, which our brain interprets as the “meaty” flavour associated with umami. Our brains have been hard-wired over the course of thousands of years to enjoy the taste of beef, so we do.
We eat with both our nose and our eyes before our mouth, and when a gorgeous steak is placed in front of you, it smells really, really good. As we eat we continue to pick up all that aroma, creating a multi-layered sensory experience.
