No, this is not an ordinary onion. This is called a "strawberry onion." In this central part of Florida, land of strawberries, this onion is planted on the edge of the fields to keep bugs and pests away from the precious strawberry crops. These onions, known only as strawberry onions, are then sold at the farmers markets in the area. They are mild, picking up a tantalizing aroma and sweetness from the berries.
They tend to be soft and disintegrate, but we slice them, doctor them with olive oil and kosher salt and pepper and grill them. They are also delightful sliced on a sandwich. A bit pricey, perhaps, $1.50 each, but we enjoy one almost every week during strawberry season.
