Knob onions, also known as spring onions or green onions, are young onions that have not yet fully developed a bulb. They have a milder flavor compared to regular onions and are often used in grilling for their delicate taste and texture. In this article, we will explore the different types of onions, their characteristics, and how to prepare them for grilling.
Types of Onions
Regular Onions
Regular onions are the most common type of onion and are typically harvested when they are young and sweet. They have a strong flavor and a high water content, making them prone to spoiling quickly.
Scallions
Scallions, also known as green onions, are young onions with a small onion bulb at the end. They have an onion-y taste but are milder than regular onions. Scallions can be used raw or cooked and are often used in Asian cooking.
Spring Onions
Spring onions, also called bunch onions, have larger bulbs at the base compared to scallions. They are taller and have a more intense flavor than scallions. While they can be used in much the same way as regular bulb onions, they are great grilled, roasted whole, or used like pearl onions.
Bunching Onions
Bunching onions, also known as Allium fistulosum, are small-bulbed onions that are often gathered into a bunch. They can be used in the kitchen in the same way as scallions or green onions but tend to mature faster.
multiplier onions (Allium cepa var. aggregatum)
Multiplier onions are similar to shallots in terms of flavor, bulb size, and growing habit. They are a type of green onion that grows as a cluster of several stems from a single set, making them about one inch across. Multiplier onions have a clear and very fresh taste and are used in Mexican cuisine, particularly in grilling and slightly charred.
Preparing Knob Onions for Grilling
Before grilling, it's important to select fresh knob onions that have a firm texture and vivid green color. Trim the roots and remove the outer layer of skin, but be careful not to peel too much to retain the tender inner layers. You can then drizzle the onions with olive oil and season them to taste with salt and pepper.
Grilling Knob Onions to Perfection
To achieve perfectly grilled knobs, preheat your grill to medium-high heat and place the prepared onions directly on the grill grates. Grill the onions for 3-5 minutes per side, or until they develop char marks and become tender. Remember to turn them occasionally to ensure even cooking.
Serving Suggestions
Grilled knobs can be served as a side dish with grilled meats or in salads and vegetable platters. They can also be chopped and used as a flavorful topping for grilled fish or tacos. You can also experiment with different flavorings, such as brushing them with a balsamic glaze or sprinkling them with crumbled feta cheese.
