5 BASIC TASTES: Sweet, Sour, Salty, Bitter, and Umami
Scientifically, Umami is the taste of glutamate, an amino acid that is one of the building blocks of protein. This glutamate occurs naturally in the human body and in many delicious foods that we eat.
The answer is pretty simple:
Umami enhances the flavours of food by stimulating taste receptors. It harmonises the tastes of all the ingredients in a dish to produce a full-bodied blend of mouth-watering sensation. It makes your food richer, fuller, and meatier.
Umami is also easy to achieve! Whether intentionally or unintentionally, we often add umami boosters to our cooking.
