I've tried editing the font of the recipe card and in the preview it does change, but it does not change once live. I'm not sure where the font comes from... It's hard to read. Specifically, the font isn't changing under the ingredients and directions heading.
Any ideas? you can see an example here: http://porchandtable.com/2013/09/20/stunning-sides-garlic-parmesan-stuffed-mushrooms/
