Is it safe to cook with rainwater


Is it safe to use rainwater as an ingredient versus tap water – or even cooking things in it like pasta? Would there be any differences in measurements or cooking times – the thought being that there are no chemicals in it versus Tap Water?

Keep in mind that tap water is tested to ensure it's safe for human consumption. Rainwater has no such requirement.

While rainwater seems to be a happy-fuzzy natural resource, I'd like to stress that this could be a serious safety issue. Yes, it seems unlikely, but you need an authority who knows their water.

I suggest seeking out a professional opinion on how to properly filter rainwater. Possibly from the people who handle your municipal water supply.
