What is the first step in assembling a spicy AM sandwich?

The first step in assembling a spicy AM sandwich is to prepare the buttered, toasted bun heel. This step is critical because it establishes the base of the sandwich, ensuring that the bun is warm and has a rich flavor from the butter. A well-prepared bun enhances the overall experience of the sandwich, as it supports the ingredients while adding texture and taste.

Starting with the bun heel allows for subsequent ingredients, such as the spicy chicken filet and toppings, to be added effectively. If the bun is not toasted or prepared properly, it can lead to a less satisfying sandwich, as the bun may become soggy or fail to hold the ingredients well. Ensuring that the heel is ready before adding other components is crucial for maintaining the quality and presentation of the spicy AM sandwich.
