To incorporate it into your mashed potatoes, fill a pot with water, add 2 grams of sugar and 3 grams of salt for every 100 milliliters of liquid, and then add peeled, cubed potatoes to simmer until tender. Then drain them, place them in a bowl, and mix in 1 gram of malt powder per 100 grams of potatoes before passing them through a ricer into a plastic zip-lock bag.
