The technique of blanch vegetables It is a cooking method that involves immersing vegetables in boiling water for a short period of time, followed by rapid cooling in ice water. This process is crucial for maintaining the vegetables' texture, color, and nutrients. It is widely used in preparing vegetables before consumption, whether in salads, stir-fries, or as a side dish. Learn the difference between vegetables and greens can enrich your knowledge about the importance of bleaching.
There are several reasons why blanching vegetables is recommended:
- keep the vibrant color and attractiveness of vegetables.
- Helps to eliminate impurities or bad flavors and reduces the microbial load.
- It facilitates the subsequent cooking or preparation of the ingredients, making them more pleasant to the palate.
- Allows you to maintain the Vitamins and nutrients mostly.
What is vegetable blanching?
Blanching is a cooking technique that involves immersing vegetables in boiling water for a short time, usually from a few seconds to two minutes, depending on the vegetable. This short cooking time allows the vegetable to soften slightly, while subsequent cooling in ice water stops the cooking process. This prevents excessive loss of texture and nutrients.

Typically, vegetables that are blanched include broccoli, spinach, zucchini y carrots, among others. This technique is commonly used in the preparation of foods such as soups, salads, and stews.
How do you blanch vegetables?
To carry out the bleaching, you will need the following ingredients and materials:
- Water, preferably with salt.
- Ice or a container with very cold water.
- A large pot for boiling.
Below are the steps required to blanch vegetables:
- In a large pot, bring at least 2 liters of water to a boil.
- Once the water is boiling, add the vegetables you want to blanch, making sure not to overcrowd the pot.
- Control the time the vegetables are in the water, which varies from a few seconds to 2 minutes depending on the hardness of the vegetable.
- Remove the vegetables from the water and immediately submerge them in the bowl of ice water. This will stop the cooking process.
It is important to avoid overusing these steps, as improper blanching can result in significant nutrient loss. For example, it has been reported that blanching can cause the loss of between 10% and 40% of the Vitamins during cooking.
Differences between blanching and scalding
The words blanch and scald are often used interchangeably, although there are subtle differences between the two techniques. Blanching involves shorter cooking times in boiling water, while scalding uses boiling water to soften or make the skin easier to remove on certain foods, such as tomatoes or almonds. In blanching, foods are quickly removed from the hot water and submerged in cold water to prevent overcooking.
Recommended blanching times
Each type of vegetable requires a different blanching time. Here's a general guide to blanching times by type:
- Spinach: 30 seconds to 1 minute.
- Broccoli: 2 minutes.
- Carrots: 1 to 2 minutes (depending on size).
- Green beans: 2 minutes.
- Cauliflower: 2 minutes.
The blanching technique is excellent for preparing vegetables for storage or use in recipes, as it improves their appearance and texture. However, it is important to adapt cooking times to the needs of each recipe and type of food.
In addition, some vegetables, especially larger ones or DensityPotatoes, like potatoes, should be cooked differently. For example, potatoes should be placed in cold water before boiling to ensure even cooking throughout. In this case, it is recommended to boil them for two minutes after the water has returned to a boil.
Advantages of blanching vegetables
Blanching provides numerous advantages in the kitchen:
- Color fixation: The blanching process also helps to set the color of the vegetables, making them more attractive on the plate.
- Softening of flavors: It is useful for softening the flavor of vegetables with a strong or bitter taste.
- Loss prevention: Blanching can help prevent nutrient loss by limiting cooking time.
- Quick preparation: It facilitates subsequent cooking by softening the vegetables quickly.
This technique is particularly useful when preparing vegetables for salads, as it helps maintain their freshness and ability to be eaten raw. It's also beneficial when using vegetables in stews and stir-fries, as it gives them an al dente texture and a vibrant appearance.
