The process involves cooking asparagus spears on a grill, utilizing aluminum foil as a cooking surface and enclosure. This technique employs indirect heat, steaming the asparagus within the foil packet, resulting in a tender-crisp texture. For example, raw asparagus spears, seasoned with olive oil, salt, and pepper, are wrapped in foil and placed on a preheated grill.
This method offers several advantages. It prevents the delicate asparagus from falling through grill grates and burning directly. The foil packet also traps moisture, creating a steam environment that helps retain the asparagus’ natural flavors and nutrients. Historically, similar cooking methods, utilizing leaves or natural wrappings, have been employed to protect food from direct heat and preserve moisture during open-fire cooking.
