How the Nutrition Machine works

The recipes with nutrition machine requires you to stand in front of a nutrition machine in order to prepare a specific recipe you want to make.

The Enter key can make and take. You will not take before making. Similarly, you will not make if the machine has items that should be taken out of.
Adding item means draw an item and press Spacebar to add into the machine.
Except the first item of the recipe, you can add other items in whichever order you like.
When adding the very first item, sometimes a menu may pop up. Select the appropriate item you want to make, then press Enter, which will add the item successfully and the selected option be prepared.
Press Alt+Space with an empty hand to get information of the machine you are standing.
After adding items necessary for the recipe you want to make, press Enter to start making. If you did not add the required items, it will tell you the name and amount of each item that still needs to be added.
After making is successful, press Enter again to take the items out of the machine.
