Yes, I know it's a volume unit, but I want to know how many grams does a male or female handful of spinach can hold. You'll see, a recipe calls for 2 handfuls of spinach, 1 handful of parsley and 2 leaves of kale (these aren't all the ingredients, just the non-precise ingredients). So, as you can see the recipe is good for you because you don't have to measure, however, I want to get the nutritional fact of this recipe. To do this, I have to put the ingredients and its quantity on a page.
So, how much is a handful of this green veggie? Or much does it weighs? (it'll also help).
