A recipe may use the same ingredient in more than one step. Keep each amount aligned with its label basis before adding nutrition. Two lines saying “one serving” can refer to different amounts if you copied them from different entries.
An invented two-step example
Suppose a label gives 100 kcal per 50 g. You use 75 g in a filling and 25 g in a topping. The filling contributes 150 kcal and the topping 50, totaling 200 kcal from 100 g. Counting both amounts as one serving would happen to produce the same energy here, but hide the wrong reasoning.
If the topping were 40 g instead, it would contribute 80 kcal and the ingredient total would be 230. The final quantity is 115 g, or 2.3 label servings. A list with two recipe steps still does not mean two label servings.
Consolidate after conversion
You can add the compatible gram quantities first and scale once, or calculate each step and then add. Both methods should agree. Use that agreement as a check before dividing the whole recipe into portions.
Do not consolidate incompatible forms
Raw and cooked entries, drained and undrained foods, or different product labels may need separate treatment. A repeated ingredient name alone does not prove identical nutrition per gram. This article’s figures are invented to demonstrate bookkeeping, not kitchen testing. Keep the current product label and actual amounts attached to the recipe so a later change can be recalculated.
