A blog about recipes should be a nice blog and easy blog to get traffic to..as suggested by others write high quality articles, submit to social bookmarking sites, good content...

One other thing that might be of use for honing in on your niche nice and quickly would be to look for other blogs...not recipe blogs but perhaps "mommy blogs" - there are thousands of them..Why not contact the blog author and ask if you can "Guest blog", tell them you want to share a lovely recipe for children at Halloween for example (although that event has just gone, so get something lined up for Christmas now or any event) so then you are adding value to the established blog with a timely recipe for your guaranteed target audience...If the moms out there try out and like your recipe they'll be heading straight to your own blog to see what else you are talking about...

One other idea, although a bit more effort and time consuming, would be to see if there is some big blogger in your area who would review your recipes...ask if you can cook one of your recipes for them and they blog about it...record their reaction as they eat it and their review...You then have a piece of footage for youtube (to open all those other doors) but the blogger you have cooked for will then write about it (hopefully favorably) and then you'll get traffic from that bloggers readers...

..just a few ideas anyway, good luck with it...
