For those that have never worked with fish sauce before here's a few tips. It is super pungent in its raw form. So much so that you will be thinking WTF am I doing, this is going to ruin my food. Once it's cooked it transforms more into a salty flavor and is nothing like it was. With that said, when mixing it, touching anything that has it on it I'd recommend gloves. The smell will linger on your skin after several washes. I'd also recommend using a plastic bag or stainless container for mixing as it will transfer the smell to plastic containers. The fact that I couldn't find the valve for my vacuum tumbler may have saved it from a super deep clean. So there us go that's the disclaimer for working with fish sauce! It's great stuff and is a great substitute for salt in many dishes.
