Hi, I made some cinnamon rolls yesterday that calls for 1/2 mashed potatoes and a cup of the water the potatoes were cooked in. They were really good, but cooking the potatoes to make them is a hassle. Would it be possible to use instant potatoes to make the potato water along with the mashed potatoes? I was thinking of maybe boiling the water and just sprinkling some of the flakes in until it gets a little body to it? What do you all think. Would this work? Thanks.
