I'm having trouble creating a custom content field in CustomPress for an ingredient list.

I'm wanting to create a custom field for an ingredient list for recipes. I've created my custom content field, but I'd like to have the input for each individual ingredient be as barney style (anybody can do it) as possible. What I essentially want is a column of 10 (for example) single line text boxes where each one is given a class of "ingredient" and a button to add more lines if needed. Does that make any sense? I can make a quick wireframe if it would help. Thanks for the help, you guys ROCK!
