For someone who is not an expert in the kitchen, I cannot tell you the difference between stock and broth, because to me, they refer to the same thing. However, there is a difference between stock and broth, and you may want to throw in bone broth and bouillon into that mix as well. From Zoe Denenberg and the editors of Epicurious, they give us a short rundown of the nuances between the two.
The main difference is simply the amount of time it takes for the liquid to simmer. Broth usually takes a relatively shorter time to simmer, from around 45 minutes to 2 hours, meanwhile stock takes 4 to 6 hours to simmer. What this does for the stock is that it allows the flavors to be fully brought out, and the longer simmer time also adds to the consistency of the mix. Apart from these two, they also elucidate the peculiarities of bone broth, bouillon, and even vegetable broth. To learn more, check out their article here.
