Given the background description of some cooking related query, summarize the question into a title

Ex Input:
The bag of coffee I am using instructs to "Add 2 1/2 tablespoons (37 ml)" of ground coffee. When I measure out 2 1/2 tablespoons onto my food scale, it only comes out to about 13 ml. Why does my 2 1/2 tablespoon measurement not equal 37 ml?

Ex Output:
Why does my 1 tablespoon of coffee grounds not equal 15 ml?


Ex Input:
I am looking at:100% peanut butter (no added salt, sugar, oils or anything else)100% roasted peanuts (no added salt, sugar, oils or anything else)When looking thought different sources, I can always notice the following:Peanut butter has more protein (as % of calories) than peanutsexample sources (I've looked through a dozen more, but please check others, maybe mine are not representative?):http://www.waitrose.com/shop/ProductView-10317-10001-5588-Waitrose+LOVE+life+roasted+peanutshttp://shop.wholeearthfoods.com/collections/award-winning-peanut-butter/products/whole-earth-100-nuts-crunchy-peanut-butte-227-gWhy is this? If no ingredients are added, how is it possible for the macronutrients to change (as % of the calories). Different levels of roasting cannot be the reason because they should not change macronutrients disproportionally.The only explanation I can think of is if in the process of making peanut butter, some part of the peanut is removed and that part contains a low protein amount. Some sources say that when peanut butter is made, the 'bitter heart of the peanut' is removed. Could that explain it?If anyone has some insight I would be very interested to learn.

Ex Output:
How can 100% peanut butter have more protein than 100% peanuts


Ex Input:
I recently got a L'Equip food dehydrator and have had some good success playing around with it. But I'm interested to know if I can dehydrate different food stuffs at the same time. For instance, could I throw jerky on one tray, onions on another, and strawberries on a third (assuming they all wanted the same time / temp) or would my strawberries end up tasting a bit like oniony beef? What kind of things would cause this contamination?

Ex Output:

Can I dehydrate multiple different types of food at the same time?
