I’m on a mission to make a porridge from every grain I have in my pantry (not really, but I probably should be). I have my favorites and this brown rice porridge is towards the top. One thing about my porridges that happens to be the case across the board: I like them thick and I like them with texture (this is also the same with my morning bowl of oatmeal).
Also, I like to use short-grain brown rice. The starch from the shorter grains helps thicken the porridge a bit more without having to cook the rice until it completely falls apart (like the method used with long grain rice in making Congee. If this sounds more your speed- I recommend checking out a congee recipe.)
