Onion (also known as red onion, flat onion or wood onion) is a kind of onion, with purple skin and multiple layers of fleshy scales inside, which has a strong spicy flavor and unique sweetness. This fragrance and sweetness are different from onions, because the scales of red onions are thinner and thinner than onions, and the spicy taste is softer.
shallot is a slender herb with edible stems and leaves. It has a strong fragrance and fresh taste, and is often used as a seasoning or seasoning in cooking. The smell of shallots is usually described as fresh, fragrant and slightly sweet, and it is more intense than ordinary onions.
therefore, between the red onion and the chives, the chives usually taste more fragrant. However, it still depends on personal taste and cooking purpose.
