Where do we start saucing on a toasted sandwich bun?

Starting to sauce a toasted sandwich bun in the middle is beneficial for several reasons. When sauce is applied in the center, it ensures an even distribution across the sandwich, preventing the outer edges from becoming overly soggy or messy. This technique also allows the sauce to blend well with the other ingredients that will be added to the sandwich, enhancing the overall flavor profile and ensuring that every bite has the right amount of sauce.

When sauce is applied to the edges or the bottom, it can lead to inconsistent coverage, making some bites dry and others overly saucy. Applying sauce to the top can also create issues, such as the sauce dripping off the sides or getting on hands, which many diners prefer to avoid. Therefore, starting in the middle provides a controlled approach for achieving the best texture and flavor experience in the finished sandwich.
