There are many people who boil ramen with tap water, right?? They say that you should never do this.
According to a survey conducted by the Ministry of Environment, 66% of households in Korea use tap water instead of purified water for cooking. You may say that it’s all the same when you boil it, but it’s different. In particular, our country’s K-tap water is clean enough to drink without any special treatment.
The problem is this hot tap water. Tap water has different paths for cold and hot water. Cold water comes out directly through the water pipes, but hot water comes out through the boiler pipes, so it is said that heavy metals, etc. can be mixed in. It is said that heavy metals such as lead remain and are not removed no matter how much you boil them. Of course, if the pipes are clean, it doesn’t matter, but if they seem a little old, I recommend boiling them in cold water.
