There are several factors that could contribute to why toast made under the grill on the cooker (broiler) might taste different or even better than toast made in a traditional toaster:
Heat Source and Coverage: The grill on a cooker provides direct, intense heat from above, covering the entire surface of the bread. This even heat distribution allows for consistent toasting across the entire slice, resulting in a more uniform and crisp texture. In contrast, traditional toasters often use heating elements on the sides, which may not evenly distribute heat or cover the entire surface of the bread.
Adjustable Cooking Time: When toasting under the grill, you can easily control the distance between the heat source and the bread, as well as the cooking time. This level of control allows you to customize the level of browning and crispiness according to your preference. In a toaster, the cooking time is often fixed, and while some toasters have adjustable settings, they may not offer the same level of precision as a grill.
Moisture Evaporation: Toaster ovens or grills often have better ventilation, allowing moisture to escape from the bread more efficiently. This helps in achieving a crispier and more flavorful toast compared to traditional toasters, which might trap some moisture inside, resulting in a less crispy texture.
Versatility: A toaster oven or grill can be used for more than just toasting bread. They can handle various cooking tasks, including broiling, baking, and roasting. This versatility might lead to a different flavor profile in the toast due to the unique cooking environment.
Browning Reactions: The direct, intense heat from a grill can trigger the Maillard reaction and caramelization more effectively. These chemical reactions are responsible for the browning and development of complex flavors in toasted bread, contributing to the enhanced taste.
Equipment Quality: The quality of the grill or toaster oven, as well as the type of bread used, can also impact the overall flavor of the toast. Higher-quality grills may have better temperature control and more powerful heating elements, resulting in superior toasting.
Keep in mind that taste preferences are subjective, and some people may still prefer the convenience and consistency of a traditional toaster. However, toasting under the grill on the cooker can offer a different toasting experience, providing a unique and delicious flavor that many people find appealing.
