How to boil frozen vegetables

If you are reading this, chances are that you have already tried boiling vegetables and turned them into a soggy mess. Well, we have a solution that will be just right for your vegetables and you.

It is interesting that while the process is the same, the technique is different for different food groups. With vegetables, you do not need to completely submerge them into water. This is because vegetables are already mostly water, and the addition of more water just makes them soggy and less flavourful. 

So your method would be to simmer the vegetables, with water level below the surface of your vegetables. Depending on how soft you want your vegetables to be, it will take about 5-7 minutes for your vegetables to be boiled to perfection.

Should you thaw frozen vegetables before cooking? 

For most vegetables, no. You should not thaw frozen vegetables before cooking. This is because it will just result in the loss of texture, giving you a soggy, sticky mess. You can put them directly in the dish. 

Another interesting thing to know is that you should add vegetables in your dish when it is near to the finished product. This is because vegetables do not take much time to cook, and they will thaw pretty quickly. So there is no reason to thaw them before cooking. 

For leafy vegetables like spinach or lettuce, you should actually thaw them before using them as a topping. This is due to the difference in purpose of the vegetable being used. You wouldn’t put frozen spinach leaves on top of pizza, right?

Boiling Hacks (Tips for boiling)

If you cook regularly, knowing when and how to boil is an essential part of your cooking regime. Boiling is a quick way to clean and disinfect food items. Not to mention that it retains original flavour while also eliminating the harmful microorganisms that may be inhabiting your food product. 

Boiling is a moist-heat cooking method when the temperature of the liquid reaches 212F. The food product is completely submerged in water for even heat distribution. It is an explosive phase change between liquid state and a gas state.

It is one of the safest and most reliable methods for cooking till date, and a lot of health professionals recommend boiling water before using it. Here are some tips that will facilitate you in boiling any food product. 

Use a food thermometer. 

Well, this is the oldest trick in the book. When boiling any particular food product, you need to make sure that the temperature is neither too low nor too high. A quick and effective way to solve this problem is by using a food thermometer. A temperature of 212F is just right for you to boil any food product. But wait! Shouldn’t the temperature be different for different food products? Well, not really.

Since the technique in itself revolves around the use of water, and you are using that heat to boil your food product, it remains pretty much the same for all food items. Of course, there can be minor changes in the temperature range, but 212F is a benchmark. 

Use salt for quick boiling

The reason you should use salt is because salt actually lowers the boiling point of water, which in turns speeds up your boiling process. It does add some salty taste to your dish, and most of the dishes use salt inevitably. So it is not really a problem unless you don’t like salt or have hypertension

Use pots reasonably

Boiling involves cooking in water, therefore you need to know when to use which pot. This actually saves you a lot of time because if you are just boiling an egg in 1 litre of water, you are just using more water than needed. Moreover, it will require more time to reach the boil. 

When boiling, make sure that your pots can be covered – avoid using pans. Using deeper pots actually help to keep the food submerged properly and evenly distribute the heat. Afterall, it is the water that is cooking! 

Other facts about boiling

On top of it being the best way to cook food, boiling actually concentrates the flavour of your food. It also allows you to cook a large amount of food with ease. Although some nutrients leach out in the water that is used in boiling, boiling does not affect the nutritional status of the food product. Just use the water that you boiled in along with the dish and you will not lose any nutrients while cooking!
