In the very early days of Chez Panisse, I knew the importance of the flavor and freshness of our ingredients, but seasonality wasn’t uppermost in my mind. The truth was, seasonality was an invisible force that we were grappling with every day, but we weren’t fully committed to understanding what it meant. The shift to seasonal cooking at Chez Panisse came with our connection to the farmer Bob Cannard, and the aliveness of the food that came into the restaurant from his farm. Part of this was because of Bob’s semi-coastal Sonoma microclimate; part was because he knew precisely which vegetables and fruits he could grow successfully at different times of the year. He would send us vegetables we didn’t even know were in season. Finding something in the winter like Bob’s carrots or chicories—which were so beautiful and flavorful—was an edible education. His ingredients made us realize that there were new and different flavors to be found, whatever season we were in.

Dump mediocrity; embrace ripeness

Ripeness is the key to seasonality. There’s a subtlety to ripeness, and it takes discernment to know when something is ripe: the right amount of give to an avocado, the color of the shoulders of the Blenheim apricot, the scent of a passion fruit. You must look carefully, evaluate the flavors, and figure out the essence. Discernment is not the same thing as judgment; it’s not merely “this is good”; “this is bad.” To understand ripeness, you have to learn through trial and error—you have to taste and taste again. As recently as 60 years ago, preserving was a skill that most families had. When you know how to cook and preserve foods, you can employ these ingredients in myriad ways. Freezing can also be used to capture a moment, as with stocks or fruit that can be made into smoothies and ice creams later in the year. Preserving food helps us all be less food insecure. And while I am completely devoted to seasonality and the primacy of localness, I do recognize the benefits of Carlo Petrini’s idea of “virtuous globalization”: buying coffee, tea, spices, chocolate, and other nonperishable goods from people in other countries who are using best farming and labor practices. People might think eating only what’s in season is unfeasible, or means denying ourselves foods we have grown accustomed to eating all year. We have been conditioned to expect the endless bounty of summer foods through every season, even though that’s simply not the way nature works. I say this all the time, but in truth, when all year long you eat those same second-rate fruits and vegetables that have been flown in from the other side of the world or grown in industrial greenhouses, you can’t actually see them for what they are when they come into season, when they’re ripe and delicious. By that time, you’re already bored. You’re eating in a thoughtless way. Letting go of this constant availability doesn’t have to be restrictive. On the contrary. It’s about letting go of mediocrity. It is liberating. Living in the season is empowering—and there can be enough local food, even in the months when there are fewer fresh ingredients available. It’s possible to prepare yourself. You need to have cool places to store sweet potatoes and apples and nuts. You need to have the forethought to capture and preserve the bounty of the harvest when it’s at its peak. Eating in season also challenges you to be inventive. I find I take much more care with ingredients when I’m eating seasonally. I’m more economical, too: I might candy the orange rinds instead of throwing them away, and I might make a broth using the green tops of vegetables and onion skins. I’m not as inclined to let things go to waste, because I know this is the one moment of the year to have that beautiful spring pea, or that September fig. I cherish it.

Be patient

Patience is obviously part of seasonality, too. Every year, we can’t wait for the arrival of our California king salmon. But we do wait. And when it’s finally in season, we have it on the menu all the time, and it is sublime. Most important, cooking like this helps us to remember that we can’t expect the salmon season to be what it has always been. The local salmon’s availability is different every year, because of global warming, overfishing, and natural environmental shifts. Two years ago, the local salmon was available for only six short weeks. We have to go with nature’s ups and downs. And when we do, we become more attuned to the bigger picture of what’s happening to our ecosystem, and we want to take care of it. The good news is there are also many ways to naturally extend the growing season. This is not the same thing as shipping food halfway around the world or building industrial greenhouses that rely on the use of pesticides. It’s a way of working creatively with our shifting seasons. One of the most extraordinary organic greenhouses I’ve ever encountered is at the Ballymaloe Cookery School, in Ireland; the sheer diversity of plants in it is staggering. It is an organic laboratory. They have taken the local agriculture around them and extended it through the winter. There are still limitations, of course—you cannot have a ripe cherry from a greenhouse in January—but your options can be expanded through skillful organic, regenerative growing practices. And it can happen all over the world. Because it is terribly important that we accept change. Everything is different all the time—when we want the world around us to always be the same, we are swimming upstream. Seasonality helps guide us and propels us to embrace change rather than dread it. When you accept the seasons, you feel the ephemeral nature of each moment and understand how fleeting and precious life is.
