The first step to getting delicious cooking results is to choose the right onion. Choose onions that are large, firm, and heavy for their size. Make sure their skin is dry and free from any signs of damage or spots. Fresh onions usually have a shiny and dry outer skin. Avoid onions that have started sprouting as their quality has deteriorated.

Slicing onions properly can affect the final result of the dish. Use a sharp knife to obtain uniform and neat slices. First, cut off the top and bottom of the onion, then divide it into two halves from end to end. Peel the skin, then slice the onion according to the recipe's needs.

"Onion can be cooked in various ways such as sautéed, roasted, or fried. To sauté, heat oil or butter over medium heat. Add the onion and stir slowly until the onion becomes translucent and soft. For a sweeter result, add a little salt while sautéing because salt helps to extract liquid from the onion, speeding up the caramelization process."

"To enhance the taste of onion, you can add additional ingredients while cooking. For example, add a little sugar when sautéing to speed up caramelization. For a richer flavor, add chicken broth or beef when sautéing."
