Pretty happy user of anylist[1] here: contains all my recipes, when I go to the shop I just select a few recipes and have a shopping list.

I haven't used the recipe feature yet, but AnyList is my go-to grocery list app. Big fan of rearrangeable aisles, preferred stores for items, and the ability to check off items in real-time on two devices in-store.

Same here, it's met my needs pretty perfectly: Fast, good search, plenty of categorization options, absolutely excellent grocery store list integration with recipes, and bookmarklet to save recipes I find online.
