Good to Know about Food Steamer

After you learn the differences between food steamers, you may need to learn something more about them so you can use the steamer to their maximum capacity. Below are some things you need to know about food steamers so you can avoid getting troubles using them. 

The Right Amount of Water

It is very important for you to put the right amount of water. If your steamer doesn't come with a timer, putting too much water will make your food overcooked and you will end up with lumpy non-appetizing food. Meanwhile, if your steamer doesn't shut automatically when the water tank is empty, putting too little amount of water may make it burn. Read the instructions clearly and be mindful when putting the water. 

Boil the Water First

Even when it seems easier to just put everything in and let the steamer run it is actually better for you to preheat the water. This way, you don't have to let the cook sit too long in the steamer. Some people wonder why the steamer produces so little steam and cooks too long, it is because they don't preheat the water. The best way you can do this is by putting the water to the tank first, run the steamer until it produces steams, then you can put your food in the bowl. 


Multi-tiered steamers are convenient. However, there are some problems that come with it. For example, the steam doesn't reach the top bowl, or the food juices from the top bowl drips to the food on the bottom. You need to be wise and arrange the food better. For example, if you cook proteins with rice, you may want to put the rice on the top. Make sure that you don't overfill the bottom bowl to make sure the steams can go through and reach the top bowl. You also need to be mindful when cooking different food together since the smell and the flavor will circulate around the bowl. For example, you better avoid cooking fish and cakes together. 


Just like any other appliances, you may need some time to get used to the steamer. But it is one of the easiest kitchen gadgets to use and you almost can't do anything wrong with it. If you are new to kitchen stuff, this product is the perfect one to buy first. You can learn so much while maintaining your healthy eating habit with ease.
