Why are hens and fowls not roasted in commercial kitchens?

The premise of your question is incorrect. Hens and fowls are indeed roasted in commercial kitchens.

Here's why:

* Roasted chicken is a popular menu item. Restaurants, caterers, and other food service establishments frequently feature roasted chicken on their menus.

* Roasting is a common cooking method. Roasting is a versatile and efficient cooking method that yields flavorful and tender results. It's particularly well-suited for whole poultry.

* There are specialized ovens for roasting. Commercial kitchens often have large, high-capacity ovens designed specifically for roasting large quantities of poultry.

While roasting is a common practice in commercial kitchens, there are some reasons why you might not see it as often as other cooking methods:

* Time constraints: Roasting whole chickens can take a significant amount of time. This might not be ideal in busy kitchens with high volume orders.

* Cost considerations: Roasting whole chickens can be more expensive than other methods like frying or grilling, especially when considering the cost of fuel and labor.

* Limited space: Not all commercial kitchens have the space for large ovens or enough prep space for roasting whole chickens.

However, regardless of these factors, it's important to remember that roasted chicken is a popular and frequently prepared dish in commercial kitchens.
