ZipList is a free online shopping list and recipe service that makes it easy to share and add ingredients with one click.

ZipList gives you the tools to create, store and share a family grocery shopping list on the web. The list can be accessed by almost any device with a web browser, or you can share it in an e-mail or SMS text message. Of course, you can also print out an old-fashioned paper list if you prefer that.

The web-based shopping list interface lets you specify which store an item is available at — you can even specify the aisle. There’s also an option to add notes about coupons or anything else that’s pertinent to whichever household member goes to the store to pick the groceries up.

ZipList hosts a recipe database with hundreds of thousands of dishes thanks to an integration partnership with Martha Stewart Living Omnimedia at MarthaStewart.com. You can pull a recipe out of the database, identify it as one you plan to make, and add the items to your virtual shopping list.

If you want to pull a recipe from somewhere else on the web, ZipList provides a Recipe Clipper bookmarklet that lets you do exactly that. Again, ingredients for the recipe will be added to your shopping list.

The ZipList website is free and ad-supported. ZipList also powers Martha Stewart’s Everyday Food: Fresh & Easy Recipes iPhone app [iTunes link], which costs $0.99.
