A condiment blend consisting primarily of oil, herbs, spices, and sometimes vinegar, is frequently used to enhance the flavor profile of submarine sandwiches. This mixture, often applied liberally, contributes moisture, zest, and aromatic complexity to the assembled ingredients. One common application involves drizzling the oil mixture over sliced meats, cheeses, and vegetables before the sandwich is fully constructed.
The utilization of such oil blends elevates the overall sensory experience by providing a counterpoint to the richer, often fattier, components of the sandwich. Its versatility allows for customization according to individual preferences and dietary restrictions. Historically, flavored oils have been employed in food preparation for centuries, serving as both preservatives and flavor enhancers. The use of these oils in sandwich making represents a modern adaptation of this longstanding culinary practice.
