Plant-Based Kitchen, In Season

You've probably heard the phrase "eat in season" from your grandmother. That advice rests on a deeper logic than it seems: a vegetable that ripens in its season is both cheaper and generally tastier, because it has had the sun, water and time it needed to complete its natural cycle. Compared with a vegetable grown out of season, or one that has traveled a long distance, an in-season vegetable's flavor and texture are usually more pronounced — this isn't a claim, it's an observation you can make in the kitchen every day.

What we mean by plant-forward eating isn't a rigid set of rules either, but a balance. The bulk of the plate is filled with vegetables, legumes and whole grains; meat, dairy and processed food find a place too, in the minority, but without being entirely forbidden. Researchers studying the eating habits of the world's longest-lived communities (such as the Blue Zones studies) observe that what these communities share is exactly this pattern: plenty of vegetables, plenty of legumes, little processed food, and a table that shifts with the seasons. It's more accurate to read this not as a miracle formula, but as a habit sustained over a long time.

Turkey's Dietary Guidelines (TÜBER) also describe the Mediterranean-style eating pattern as a model centered on vegetables and legumes, with olive oil as the main fat source. For us, this feels less like a distant theory and more like an official confirmation of something our kitchen already knew. In the coastal villages of the Aegean and the Mediterranean, grandmothers' tables already followed this pattern: whatever was in season is what got cooked, olive oil was used generously, and meat was as special as a holiday meal.

In this book, we won't put you on a diet. We want to say from the very start that no vegetable will cure a disease, and no recipe has a miraculous weight-loss effect. The only thing we promise is to show how adding one more plant to your table can, over time, turn into a genuinely enjoyable habit. The rest will take shape in your own kitchen, at your own pace.

In the next chapter, we look at the roots of this pattern — the heart of the Aegean table: olive oil.

The most distinctive trait of Aegean cooking is that it never rushes. An olive-oil dish usually calls for long, slow cooking; the vegetable simmers in its own juices, over low heat, patiently. This slowness isn't a shortcoming — quite the opposite, it's the method itself, allowing the vegetable to soften while keeping its own flavor and texture. Recipes like Olive-Oil Leeks (Zeytinyağlı Pırasa), Olive-Oil Artichokes (Zeytinyağlı Enginar), or Olive-Oil Fresh Fava Beans (Zeytinyağlı Taze Bakla) are the finest examples of this patience: a simple onion-carrot sauté, plenty of olive oil, a bit of sugar-salt balance, and time.

Here, olive oil isn't just a cooking fat — it's the dish itself. In Aegean and Mediterranean cooking, olive oil is used both during cooking and added again after the dish has cooled, just before serving — this second addition matters both for aroma and for the dish's sheen. TÜBER notes that, among liquid oils, olive oil is the primary fat source of the Mediterranean-style eating pattern; in our kitchen, this has already been the preference for centuries.

Another distinctive feature of olive-oil vegetable dishes is that they're served warm or cold, not hot. This offers a practical advantage — you can prepare them a day ahead and let them sit in the fridge, where the flavors settle in even further — and it also brings a refreshing quality to the summer table. Cooking dishes like Olive-Oil Borlotti Beans (Zeytinyağlı Barbunya) or Olive-Oil Celeriac (Zeytinyağlı Kereviz) a day ahead and serving them the next day both improves the flavor and eases the kitchen workload.

Here, patience stops being a virtue and becomes a practical tool: preparing one or two olive-oil dishes over the weekend and serving them cold during the week saves time and lightens the burden of cooking something new every single day. In later chapters, especially Chapter 8, we'll go into detail about how we translate this logic into a weekly menu.

Now let's move on to the order of the seasons — starting with winter's roots and greens.
