For most of culinary history, Western cooking recognised four basic tastes: sweet, sour, salty, and bitter. In 1908, Japanese chemist Kikunae Ikeda identified a fifth — a savoury, mouthwatering depth he named umami, from the Japanese words for “delicious taste”.
What Umami Actually Is
Umami is triggered primarily by glutamate — an amino acid found naturally in many foods — and by ribonucleotides such as IMP and GMP. When these compounds interact with taste receptors on your tongue, they create a sensation of depth, roundness, and what many describe as a coating richness that makes your mouth water.
The Most Umami-Rich Ingredients
- Parmesan — one of the highest glutamate concentrations of any food (1,200mg per 100g)
- Tomatoes — especially concentrated as paste or sun-dried
- Soy sauce — fermentation amplifies glutamate dramatically
- Miso — deep, complex, and extraordinarily versatile
- Anchovies — melted into a sauce, they disappear completely but leave profound depth
- Mushrooms — especially shiitake, dried porcini, and dried mushrooms of all kinds
- Fish sauce — the secret weapon of Southeast Asian cooking
- Worcestershire sauce — contains anchovies, tamarind, and many umami-rich fermented ingredients
- Kombu (dried kelp) — the base of Japanese dashi stock
Umami Stacking
The most powerful technique: combine multiple umami-rich ingredients in the same dish. A tomato sauce that also contains anchovies and Parmesan rind will taste dramatically more complex than one made with tomatoes alone. This is why Bolognese, with its combination of meat, tomato, and often Parmesan, is so deeply satisfying.
You do not need to add salt if you have added umami. Many umami-rich ingredients are already salty — and they bring much more than salt alone ever could.
