Does MSG make a big difference? Not really but yes it does. Let's say, you and I make your favorite recipe. I add MSG and you don't. Next we have our families taste them both. Although no one will be able to put their finger on it, Everybody will tell you My dish is better.
I tested this with my crew. I mixed S & P, only, into 2 pounds of Ground Beef. I split the batch then added 1 teaspoon MSG to half. I then made Sliders, seared on a CI griddle. Each had one slider, plain, one With and one Without MSG. It was unanimous, the Slider with MSG was just Better. It tasted Beefier and more full flavored.
Glutamate is a naturally occurring Amino Acid. Our bodies naturally crave it not only because it contributes to Protein Building but it Tastes Good! Our very first taste of Glutamate is at Mother's Breast, or drinking any Milk for that matter, and we are Hooked. A thousand generations of Italians have been boosting Glutamate in food for centuries. Pasta with Garlic and Extra Virginia Olive Oil tastes great. Add cooked Tomatoes, high Glutamate, and it taste Better. Add 2 year Aged Parmaggiano Reggiano, SUPER high in Glutamate and the Flavor Explodes!!!...JJ
