Today: five new iPhone/iPod Touch apps for the home cook - apps that can be used on the upcoming iPad! I just love how the Apple developer community keeps making such useful tools for cooking and food shopping. Read on to see a very useful food inventory/shopping list, a way to buy wine from your handheld, and Michael Ruhlman's useful ratio calculator.
• Tap Grocer - a grocery list that helps you keep track of items in your pantry and refrigerator. When an item is marked as "gone" in your inventory, it is automatically added to your shopping list - no need to retype it in!
• Turkey Timer - enter the weight of your turkey and mark whether it's stuffed or not, and this app will tell you how long to cook it at what temperature, and it will remind you when to baste.
• Michael Ruhlman's Ratio App - a calculator that helps you figure out how much of each ingredient you need in order to customize a recipe to serve as many as you need. Have a recipe that says "Serves 6" but you have 21 people coming? Ratio App will help you figure out how much to make.
• Wine.com - find, learn about, and buy more than 45,000 wines right on your iPhone/iPod Touch and have them delivered to your doorstep. (I ordered a case of wine while I was riding the bus!!)
• CookWell - an app for beginner/noncooks; the easy lessons ("modules") teach you how to shop, plan a menu, and create easy, healthy meals and snacks.

It would be great if AT would focus on Android apps, too.
That's a good idea, I'll look into that.
You're missing the single most important iPhone cooking app:

Epicurious has a great app. Would be wonderful if the kitchn did too.
I absolutely love MacGourmet! I can't imagine how well it'll work with the iPad!
I have a few cooking apps...mostly they're just recipes
vegan yum yum
whole foods
...and I can't remember the other ones. :) Vegan Yum Yum has really delicious stuff, and I'm not even a vegan but I use her recipes all the time.
Agreed on the need for apps for the Droids -- I've yet to find any great cooking (or restaurant) apps for my new phone, I'm so disappointed!
jaime oliver's 20 minute meals app!
I love michael ruhlman's ratio app, but I don't think you can actually use it to do what you describe. It doesn't let you scale any recipe. It gives you a bunch of base recipes that are based on a list of ratios. It gives you the basic methods and lets you make your own notes and save your own recipes. It does also do scaling for the ratios that it supplies, but I haven't figured out a way to create my own.
I've used the Ratio app to make some amazing breads.
