Perhaps I was not precise about my comment on the nutrition information. It seems, under "nutrition facts" the text "x servings in this recipe" does not changed if you scale the recipe. You are right of cause that the size of a serving should not change, but the number of servings should. Same for "Nutrition by Ingredient": It stays static as well. E.g. take pizza dough: Default is 10 servings and the base recipe calls for "2 ¼ teaspoon active dry yeast" -> nutrition facts shows: "2.25 teaspoon Active dry yeast - 2.25 teaspoon Leavening agents, yeast, baker's, active dry | 3 calories per serving". Now multiply the recipe, say for 40 servings. Recipe now calls for "9 teaspoon active dry yeast" (as expected). But nutrition by ingredient still shows: "2.25 teaspoon Active dry yeast - 2.25 teaspoon Leavening agents, yeast, baker's, active dry | 3 calories per serving" (not wrong, but kind of misleading). And "Nutrition Facts" still mentions "10 servings in recipe" instead of 40. HTH
