Cooking is chemistry, only delicious. You might think this traditionally domestic pursuit isn't geeky, but you're wrong: combining cheap ingredients into a delicious meal is the ultimate life hack.

Today Cool Websites and Apps is looking at five sites with a wide array of recipes, teaching you to make everything from pad Thai to pizza. Whether you're looking for easy healthy recipes, soup recipes or anything else, one of these sites has you covered.

We've gone over recipes apps for Android before; more than once, actually, so today we'll focus on the web and the iPhone. Let's get started.

Gracipe: Step-By-Step, Diagramed Recipes with Built-In Timers

If you bring your laptop or phone into the kitchen so you can follow recipes, Gracipe is for you. There are lots of recipe sites on the web, most of which might as well be paper books for all their interactivity. Gracipe offers a visual, interactive approach.

Here's a short excerpt from a recipe, just to give you an idea:

There are hand drawn icons for every ingredient, as you can see, as well as the tools you need to use. Instead of just listing how long you should cook something, Gracipe offers a functional timer – click it and it will start counting down.

The recipes offered here are pretty limited, but you can get access to more by signing in. You can also add your own recipes.

NYT Cooking: Browse and Clip 17,000 Recipes

Whatever you think about The New York Times, you have to admit they publish a lot of great recipes. NYT Cooking is a free site you can use to browse those recipes.

There's a lot to explore here, organized in all sorts of categories, so dive in. Alternatively, if you know what you want to make, use the search. If there's something you've been wanting to make, you can probably find a few recipes to try here.

A nice feature I wasn't expecting is Evernote integration. Sign in and you can authorize the site to sync to Evernote, meaning everything you save ends up in a Notebook on all your devices. And it works the other way: any recipes you have in Evernote show up on the NYT Cooking site as well.

If you use Evernote regularly, this feature alone is worth it.

Noodles: Clip Recipes from Anywhere

If you like the idea of clipping recipes, but aren't interested in Evernote, Noodles is worth looking into. This site lets you clip recipes from anywhere around the web and explore them later. The formatting, once you do this, is quite nice.

You can share links to your re-formatted recipes, if you like, and even compile them into collections.

Ratio (iOS): Customize Your Serving Size

Sometimes you don't want to make an exact serving: you just want to throw some ingredients together and make something. Ratio is a cookbook focused on just this idea, teaching you the ratios to make things like doughs and sauces.

The app lets you enter an amount for any one ingredient, then does the math for other ingredients. Some reviewers are disappointed in how few things are offered, but if you'd like a quick way to learn a few tricks this $5 might be worth it for you.

Recipe Writer: Write, Format and Share Recipes

If you've got a recipe you'd like to share with the world, Recipe Writer is a simple tool for the job. The process is really simple, so if you've got a friend who's great at cooking but not great with computers this might work for them.

You probably know at least a few recipes you'd like to share with friends, but never get around to actually doing it. This site might make that a little easier.

What Are Your Favorite Recipes Sites?

I could go on and on, because we've compiled all sorts of cooking resources over the years. There are plenty of YouTube stations that teach you how to cook, and even sites that point out camping recipes. You could even start your own recipe blog.

But I don't want to re-hash stuff we've covered before: I want to learn new things. So I hope you'll point out some other great recipe resources in the comments below, along with any of your favorite meals. I'm looking forward to it!
