Fill up on dozens of free samples (wild blueberry jam, tapenade, caramel sauce) at the flagship store of the Stonewall Kitchen specialty foods empire, just off US 1 in-between York Village and York Harbor. Or tuck into a bowl of housemade granola or a lobster Cobb salad at the excellent on-site cafe.
You can peek at the production facilities here, too. Check online for cooking demonstration classes; these run throughout the year and cost around $50 to $60, including your meal.
