Three of the most common onions you need to know
White Onions
These are usually the mildest onion varieties, so we like to use white onions in salads and sandwiches. Basically, if you want to eat onions, white onions are what you want. Although they are mild in themselves, you can tame the flame by slicing them thinly and soaking them in cold water for an hour - they will be sweet and you can eat them almost as much as a salad. You will also see that Vidalia and Mauri onions belong to the same category as white onions. Although they are white onions, both varieties contain higher sugar content and lower sulfur content. Maui onion and onion should be used when recipes require special "sweet onions", but white onion will be a good subspecies.
shallot
Sweetness is the biggest advantage of red onions. The clarity and intensity of the flavor are slightly stronger than those of white onions, but the sugar content is much higher. This natural sweetness makes them a major candidate for pickling, and we like to be involved in tortillas, pizza or fried rice. Another obvious red onion is its color. Dark red provides a color that other onions don't have.
When it comes to barbecuing, red onions are our first choice. Cut into wedges, they grill well on the grill, and their interior texture becomes dry rather than pasty, like white and yellow onions.
Yellow Onion
You don't want raw yellow onions. We cook these onions 100% of the time, respecting the health and well-being of our noses and taste buds. Although the yellow onion (also known as Spanish onion) tastes great in its unique way, it has a very high sulfur content. This strong clarity paves the way for the sweet onion flavor, which is why we prefer yellow onions when we caramel them. Compared with white onions, Caramel yellow onions bring a significantly higher number of flavors.
