Which of the following is an example of seasonal food?

Fresh berries harvested at peak ripeness exemplify seasonal food because they are typically available only for a limited time during certain months when the weather and growing conditions are optimal. Seasonal foods refer to ingredients that are harvested and consumed within a specific season, and fresh berries often reach their peak flavor and nutritional value during that time. This concept supports local agriculture and promotes the use of ingredients that are freshest and most flavorful in cooking.

In contrast, frozen peas, while derived from seasonal crops, are preserved and available year-round, making them not a true embodiment of seasonal food. Imported avocados can be available at any time regardless of the local season, as they are brought in from regions where they are in season, thus not fitting the definition of seasonal. Canned vegetables are processed and can be stored for long periods, thus also lacking the inherent limitations and freshness associated with seasonal foods.
