TARARNDIR  SousChef implements service as per Apple's documentation. As far as I know there is no way that launching a service can crash another app. I think this is probably an unrelated issue with TextMate.  
(Version 1.2)

TARARNDIR  Check out the release notes for 1.2.

We've added metric support and improved the import parser a lot in this release. We've also fixed some crashes in the recipe editor and improved the stability of several other parts of the app.  
(Version 1.2)

TARARNDIR  We are hoping to build out the parts of the recipe we search. Currently a full text search isn't possible, but the 1.0.2 update searches a lot more of the recipe than previous versions (although *not* full ingredient text). We'd like to get full text searching into our first major feature update (which will be v1.1), but we're also working hard on grocery list support and developing an iPhone sidekick app.

Thanks for the feedback and just to reiterate, this is something we're working on.  
(Version 1.0.2)

TARARNDIR  We're planning on adding this feature and are looking into an iPhone sidekick apps to go along with this as well.  
(Version 1.0.1)
