Allow your readers to easily print your recipes. Generate a recipe index automatically instead of constantly updating it by hand. Show off your yummy food photography in your archives and not just in your posts. Here are some of the services I recommend for food bloggers.
PLEASE NOTE: These options are for self-hosted WordPress users only. If you are using another blogging platform, please inquire about your options.

Make your recipes easy for visitors to print. Example: This blog post has a print-friendly page here.
Automatically generate an index of your recipes instead of manually adding links every time you update. There are several options available:
1) List all the recipes alphabetically. Example: Year of Slow Cooking » Recipe Index
2) Lists all the recipes, but break them into different categories (like soup, salad, desserts, meat, etc.). Example: Tasty Eats at Home » Recipe Index
3) Have thumbnail images appear next to each recipe. Example: Newlyweds Blog » Recipe Index
Show off your food photography in your archives to draw visitors in and make them more likely to click on your links.
Example: Daily Bites Blog » Desserts Archives
