<aside> 💡 Since the recipes always add 1 of each ingredients, you can temporarily add extras by enabling the “how many extras” property and adding extra items, if some recipe needs multiple instances of a certain ingredient. However, this is only a manual reminder and will only add the extra ingredients to the manual list.

(I haven’t figured out a way to add a property to each recipe which would add a specific amount of ingredients to the shopping list automatically.)
