Whisk sugar, cornstarch, powdered milk, and salt together in a 3-quart saucier. When no lumps of cornstarch remain, add exactly 14 ounces of the milk (about 1 2/3 cups; 396g) and whisk to combine. Cook over medium heat, whisking constantly but not vigorously, until it begins to simmer. This will take about 6 minutes; if the process seems to be moving slowly, simply turn up the heat. When the mixture comes to a boil, set a timer and continue cooking and whisking for exactly 1 minute. This ensures the cornstarch is fully hydrated.
