Final answer:
Fresh fruit served with cold cereal is commonly called a topping. It enriches the cereal with flavor, texture, and nutrition. Fruit toppings can be simple or aggregate fruits, but terms like accessory fruit and exocarp are more technical and related to botany.
Step-by-step explanation:
When fresh fruit is served with cold cereal, it is most commonly referred to as a topping. Fresh fruit toppings can include a variety of simple fruits, such as sliced bananas or berries, or aggregate fruits like raspberries or blackberries. In this context, fruit is not considered a side dish, garnish, or condiment, but rather an ingredient added to enhance the flavor, texture, and nutritional value of the cereal.
The term accessory fruit refers to a fruit where the edible part is not generated solely from the ovary but also from surrounding tissues, and exocarp, or pericarp, is the outermost covering of a fruit. These terms are more technical and are usually used in the context of botany or food science.
