What is the second step to manually converting a recipe to a specific number of portions?

The second step to manually converting a recipe to a specific number of portions is to break down the ingredients into weights and measures. This step is crucial because it provides a clear understanding of how much of each ingredient is required for the desired number of portions. By calculating the precise amounts, you ensure that the recipe maintains its intended flavor and consistency when scaled up or down. This process typically involves measuring ingredients accurately, which allows for consistency in results, ensuring that each portion retains the quality of the original recipe.

In contrast, adjusting cooking times is an important consideration after determining the quantities of ingredients and is typically informed by the size and volume of the finished dish, rather than being the second step. Preparing a shopping list and summarizing preparation steps are also actions that would be taken after establishing ingredient amounts, making them subsequent steps in the recipe conversion process.
