What constitutes the customary accompaniments of a full English breakfast?

The customary accompaniments of a full English breakfast are items traditionally served alongside the core components to complete the plate without defining it. These commonly include baked beans, grilled or fried tomatoes, mushrooms, fried bread, bubble and squeak, and toast. While none of these items is required individually for a breakfast to meet the core definition, their presence reflects the established structure and balance of the traditional English breakfast as it has been served in homes, cafés, and hotels for generations. Accompaniments support the meal by adding contrast, moisture, and substance, and their absence may result in a reduced or partial presentation rather than a fully realised plate.
