## What is Ratio?

Free yourself from recipes! The best-selling cookbook, Ratio: The Simple Codes Behind the Craft of Everyday Cooking, by me, Michael Ruhlman, is now an iPhone app that will help you calculate amounts of ingredients in all the fundamental culinary preparations.  When you know a ratio, you don’t know a recipe, you know 1,000.  And this application does all the calculating for you.

 “Cooking, like so many other creative endeavors is defined by relationships.  For instance, knowing exactly how much flour to put into a loaf of bread isn’t nearly as useful as understanding the relationship between the flour and the water, or fat, or salt.  That relationship is defined by a ‘ratio’ and having a ratio in hand is like having a secret decoder ring that frees you from the tyranny of recipes. ….Michael Ruhlman, in handing us mortals a power better suited to the gods, has changed the balance of kitchen power forever.” —Good Eats host Alton Brown

### 1/5 — Fail

*2024-12-16, version 2.0.7*

I’m shocked that Rhulman created this, it’s missing SO much. No grains, legumes, rice, pasta. Also, it gives the option to “create your own ratio” but only gives you a prefilled dropdown list of ingredients, you are unable to fill in your own. Useless and now I’m out $4.99!

### 3/5 — No search function

*2022-09-22, version 2.0.7*

Hiya, I know it’s not a huge list to look through manually but how’s about a search function? Also, it would be ideal to have some ratios in here for cooking different kinds of rice, lentils, la la la.

### 3/5 — Not bad

*2020-06-16, version 2.0.7*

Great for ratios and conversion but no way to save recipes.

### 5/5 — Recipes & Ratios

*2019-08-27, version 2.0.7*

Great app for on the fly cooking. Read the book to get the most from the app. I weigh the eggs in a bowl as well as the liquid, like milk or cream. When using the volumne setting, I place the eggs in a measuring cup to prepare the dish. Weighing is more accurate for large portions. Volume is easier for home cooks fixing dinner. It's a handy tool to have.

### 4/5 — Good. Needs pizza dough

*2018-12-07, version 2.0.7*

Seems to be comprehensive. But it really needs pizza dough in the app.

### 5/5 — No need for recipes, I’ve got ratios!

*2018-12-06, version 2.0.7*

Highly recommend you read the book Ratio to understand how great this app is. Knowing basic ratios allows you to cook on the fly, to tweak dishes and make them your own. Example: rice. Liquid to dry rice 2:1. I’ll make a chicken &sausage jambalaya with two cups of rice. I’ll need 3.5 cups liquid plus the .5 cup liquid the onions, bells and celery will throw off. I’ll sauté up a pound each chicken and sausage, sweat the vegs and the stock, and the rice. Ka-BOOM!

### 5/5 — Chef Jim

*2018-04-29, version 2.0.7*

This an excellent cheat sheet.  Works very well.

### 4/5 — Loved the book

*2017-05-15, version 2.0.7*

Nice app that has the book published ratios.  Very convenient

### 5/5 — Back in action

*2017-01-10, version 2.0.5*

Solid app and information.

### 1/5 — Recent update killed it

*2017-01-06, version 2.0.4*

(iPod 5th gen)
Just updated this & now all of the categories are blank. I was about to use it to make bread, but saw the update & opted to do that first. Wish I hadn't.
