When I was a kid, and later during my dietetics education at UCLA, I learned about the four basic tastes in foods – sweet, sour, bitter, and salty. Relatively recently a fifth taste, umami, joined the classic four. Umami translates as “savory,” and it’s hard to describe in words. To borrow from United States Supreme Court Justice Potter Stewart ‘s “I know it when I see it” (referring to obscenity), you’ll know umami when you taste it. Think about how ingredients like aged Parmesan cheese or soy sauce bring out the flavor in a dish, a bit like the difference between musical notes played one at a time or in a chord. That’s umami. Ingredients and foods that contribute umami include meat, fish, aged cheeses, mushrooms, tomatoes, certain other vegetables, and monosodium glutamate.
Speaking of flavor and taste, if vision and hearing decline as we get older, what happens to our sense of taste? Sure seems like it gets duller — foods just don’t taste the same as they did when I was younger. Scientists are not yet sure why this happens, but a research group at the University of Groningen in the Netherlands recently found that the brain of an older adult is less efficient than that of a younger adult at registering and integrating signals from the taste buds. The taste buds are talking but the brain isn’t listening. So you might find yourself looking for ways to bring out flavor in foods. Butter and salt are the best friends of many a chef, but most of us could do without the extra fat, calories, and sodium.

Earlier this week, I invited my neighbors over to see whether we could coax more flavor out of unseasoned chicken, plain baked potatoes, and an undressed avocado – without using salt or butter. The ingredients at hand were lemon juice, onion powder, garlic powder, a lighter-flavored Arbequina/Picual EVOO blend from Marques de Griñon and a zesty Picual EVOO from Castillo de Canena. (The oils were gifts from a sponsored dinner.) Here’s what we discovered:
- Caramelizing the exterior of the chicken brought out its umami. The Picual combined with a squeeze of lemon juice paired beautifully with the chicken. No salt needed here.
- The potato provided a neutral canvas for each oil, but each potato-EVOO combo tasted even better with a sprinkle of onion powder.
- The spiciness of the Picual was a perfect match for the avocado.
- The potato and avocado combos were just fine without salt, but the tiniest finish of a few grains of sea salt – barely enough to make a sodium difference – made them even better.
Since I was playing with olive oils, I decided to toss together a quick salad. My good friend Jacques is a master at dressing salads and he inspired me to create my own rather than buying store-bought dressing. Here’s what I do:
Put greens in a bowl. I’m using a baby kale mix.

Add 1 tablespoon extra virgin olive oil. I chose the Picual because its strong flavors will stand up to the kale. Toss well until the greens are well-coated. This helps protect the leaves from a concentrated burst of the other ingredients.
Squeeze the juice of 1/2 lemon over the salad. Toss well again.
Sprinkle the salad with 1/8 teaspoon of salt, max, and several grinds of fresh black pepper. Toss, serve and enjoy!
