“The Surprising Benefits of Cooking Vegetables in Oil: A Chef’s Perspective”

Many people think that oil is only necessary for stir-frying, deep-frying, and assume that it is not needed for boiling. However, adding a small amount of cooking oil during the boiling process can enhance the taste and appearance of boiled vegetables and fruits.

Adding cooking oil helps retain the vibrant colors of boiled produce. Here’s what you need to know:

One of the biggest concerns when boiling vegetables and fruits is the loss of color, resulting in a dull, yellow, or dark appearance. To address this, ensure that you use enough water to completely submerge the produce. Insufficient water can lead to uneven cooking and discoloration. Additionally, maintain a high enough temperature so that the water quickly returns to a boil after adding the produce, ensuring vibrant colors.

When boiling vegetables, adjust the heat to the maximum setting to bring the water back to a boil quickly, preserving the colors. Adding a pinch of salt to the water enhances the flavor and further helps retain the colors of the produce.

The secret ingredient? Cooking oil. While the above steps can help achieve naturally colorful boiled produce, adding cooking oil takes it a step further by creating a protective barrier. This barrier not only prevents bacterial contamination but also slows down the oxidation process, keeping the vibrant colors intact for a more extended period.

Why does cooking oil work?

Oil and fat have the unique property of creating a protective layer around food, inhibiting bacterial growth and preserving colors. By adding oil or fat during the boiling process, you not only enhance the natural colors of the vegetables and fruits but also prolong their freshness.

To maximize the effect, add the cooking oil just before removing the produce from the boiling water. This simple trick ensures that your boiled vegetables and fruits remain soft yet firm. Additionally, after boiling and draining the produce, it is essential to spread them out on a large plate to promote evaporation. Avoiding prolonged exposure to steam also helps prevent discoloration.

Adding oil or fat will create a layer of fat on the surface of the boiling water, which some people may not prefer. Therefore, it is essential to use this technique flexibly. If you are preparing a feast or cooking for a large group, using cooking oil is advisable to keep the food fresh and colorful for a more extended period. However, if you plan to consume the meal immediately after cooking, you can achieve satisfactory results without using cooking oil by following the previous steps.

Another tip to preserve the colors of boiled produce is to immediately immerse them in ice water after removing them from the boiling water. This rapid cooling helps lock in the colors. However, it is important to note that this method can increase the risk of bacterial growth, so it is not recommended if you plan to store the boiled produce for an extended period or consume it at a later time.
