• Green Onion: Also known as scallions, green onions provide a fresh, herbaceous flavor with a delicate crunch.

Choosing the Ideal Onion: A Matter of Taste and Texture

The best onion for your roast beef sandwich ultimately depends on your personal preferences. However, consider the following factors when making your decision:

• Flavor: Yellow onions provide a classic, balanced flavor, while sweet onions offer a more subtle sweetness. Red onions add a bit of sharpness, and shallots bring a hint of garlic.
• Texture: Yellow and sweet onions have a firmer texture, while red onions and shallots are slightly softer. Green onions provide a crisp, refreshing crunch.
• Size: The size of the onion will determine how many slices you can get. Choose a medium-sized onion to yield about 1/2 cup of sliced onions.

Slicing Techniques: Mastering the Art of Precision

Once you have chosen your preferred onion, the next step is to slice it properly. For even distribution of flavor and texture, follow these slicing techniques:

• Thin Slicing: Slice the onion thinly against the grain for a delicate crunch and even distribution of flavor.
