Duplicate custom fields in custom post types

Hi there,

I’m playing around with custom taxonomies and custom post types, and have this idea that I just can’t seem to get to work.

I’m working on a WordPress recipe manager, and would like the ingredients to be a custom taxonomy. However, I also want to add measures to the ingredients, which shouldn’t be included in the custom taxonomy (as “1 cup of sugar” and “2 cups of sugar” would then be two different taxonomies).

Is there any way to create a section with duplicatable custom fields with 3 custom fields in each section (amount, measure, and ingredient)?

I’ve created a mockup to illustrate it.

Thanks!
