Seasonal is a question about where the food was grown, not what month it is. USDA's Economic Research Service records that California supplies roughly 90 percent of US fresh strawberries and produces close to year-round, with peak harvest running from early spring into fall, while Florida's season opens in November and runs through March (USDA ERS). So a January strawberry is in season somewhere. The condition that changes the answer: when you want food grown near you, the useful question is the shipping point, and the seller either knows it or does not.

Two states cover most of the calendar

What the ERS chart-of-note actually supports, laid side by side.

ERS also records that California shipments in 2019 ran 220 percent above 2000, with production extended from July to October on higher-yielding varieties and less acreage. Two states, better varieties, and the shelf stops having a season at all.

A regional calendar has to name its region

Oregon State University Extension's June garden calendar tells growers to pick ripe strawberries regularly to avoid fruit-rotting diseases, and it says at the top that its tips do not necessarily apply to all areas of Oregon (OSU Extension). The same page puts irrigation at 0.25 inches four to six times a week from June through August, and warns that frost can still reach higher elevations in central and eastern Oregon in June.

One state, one month, and the guidance already needs a qualifier about elevation. Carry that into your own notes: write the region beside the month, every time. A list that says "strawberries: June" has thrown away the part that made it usable.

Shun names a peak, not a rule

Japan's Ministry of Agriculture, Forestry and Fisheries describes shun as the point at which an ingredient such as a vegetable or a fish is at its seasonal peak, at its tastiest and most nutritious, and it names the phases around it: hashiri for the early part of the season and nagori for its end, when an autumn eggplant is described as deep in flavor and sweetness (MAFF).

That is a located way of paying attention, from one ministry describing cooking in Japan. It is not a calendar for a US kitchen, and nothing in it asks you to import an ingredient. The portable part is the habit: notice which week a food tastes like itself, and notice when that week has passed.

A two-line card for one food

Pick one food you already buy and fill in two lines, one from a source and one from the store.

  1. Source line. The growing region, the months, and the institution that says so. For strawberries: California, year-round with a spring-to-fall peak, USDA ERS.
  2. Store line. Today's date, the growing location printed on the package or given by the seller, the form, and the price you would pay again.

When the second line comes back blank, write "unknown". An honest result — "I bought berries today and cannot call them locally grown" — is a finished card, not a failed one.

What the answer changes at the store

Sometimes nothing, and that is a legitimate outcome. USDA records a cup of raw strawberry halves at 152 grams, 89 milligrams of vitamin C and 3.0 grams of fiber (USDA FoodData Central), and those figures do not move because of the state on the clamshell. What moves is flavor, price, and whether the fruit survives the week.

So use the answer for the decisions it fits. Buy fresh when the texture is the point and the week has room for it; keep the frozen bag for the mornings that do not, a trade covered in fresh, frozen or canned for tonight. Let the season change what a side dish is made of rather than whether there is one, the ordinary case in a vegetable side does not need to replace the meal. And keep the borrowed idea attributed to the place it came from, the way a grain keeps its name in one grain, several food stories.
