A cooking app with absolutely no recipes. Instead, KnowledgeBook: Cooking contains all the little bits of information and rules of thumb that you need to really use and understand your recipes -- what can be substituted for buttermilk or baking soda in a pinch, how many bananas it takes to make 1 cup of slices, how many cups are in a pint, what temperature an oven should be set to if the recipe calls for a "moderately hot" oven, etc.

KnowledgeBook: Cooking compiles all this information in one place, and adds much more: what can be substituted for buttermilk if you don't have vinegar? How many US cups are in an Imperial pint? (or an Australian pint?) What does it mean to papillote something? How should a slow cooker recipe be adjusted at high altitude? What temperature in Fahrenheit does Gas Mark 6 on a British stove correspond to?

With sections for Yields and Equivalents (including canning yields), Substitutions, general cooking terms, Measurement conversions, and High-Altitude considerations, KnowledgeBook: Cooking aims to be a one-stop reference for all the "extra" information needed to help you understand your recipes and get to Cooking!

What people are saying about KnowledgeBook: Cooking:

"It's almost become indispensable. I've used every feature. If you cook, bake, or can, you NEED this!"
("Samsnona", KnowledgeBook:Cooking 1.2.0, May 2012)

"This app is a must have for any one who calls his or herself a culinarian whether a novice or a professional. I love that the app reveals yields, substitutions and relevant and different information for cooking instead of only recipes."
("HI Life", KnowledgeBook:Cooking version 1.2.0, Jul 2012)

"As a caterer, I have found this app to be very valuable...I love the yields for produce. It's great to know how much of a fairly expensive item I will need to make a recipe. This cuts down on waste a great deal and saves me money."
("Phoenix 1972", KnowledgeBook:Cooking version 1.10, Feb. 2011)

"I have installed a similar app but this one is much better. It's really useful in cooking."

("Cheeksnes", KnowledgeBook:Cooking version 1.0.1, Jan 2011)

"Awesome app! The best cooking reference app I've ever used all wrapped up in a beautiful FREE bow! It's actually better than most of the paid cooking reference apps and those don't offer HALF the info this one does. A must have for anyone who cooks!"
("Tatem214", KnowledgeBook:Cooking version 1.0.0, Dec 2010)

Wholly Underrated App

I honestly don't remember how I found this app or why I would've downloaded it in the first place, but it has become my favorite cooking resource, hands down.
Most frequently I use the Yield and Substitution sections. It's convenient to have an offline app for reference at the grocery store or to quickly find a substitute to avoid a kitchen disaster.
The interface could certainly use an update, as the feel is old and awkward, but I do appreciate the straightforwardness of the menu. To my memory, I've never seen one ad or been asked to rate the app in a popup.
I was going to give it 4 stars but decided on 5 because of how underrated I think this app is.
Thank you! I really appreciate this app.

Good content, but it crashes

The app itself is one one of the most helpful and comprehensive cooking apps out there, but it sometimes crashes when you open it. Annoying, but doesn't change how awesome this app is.

Very Informative app that needs update to 64-bit

This apps is really useful. I just wish Apple or the developers would update it to 64-bit for it to be compatible with iOS 11.
