How to show featured products from a certain category only?

Question

How can I show featured products from a certain category only?

I managed to create 'featured product' as one of the attributes for my products and I have 'tagged' a few products to this attribute. But my problem is I only want to show the featured product from one particular category only.

I have 'wine', 'food', 'gifts', etc as my categories. And each category has their own featured products, so when I am on wine category view page, I want to show the featured ones from wine category only, and then I want to show the ones from food category only when I am on food category view page.

I followed the guides here to create 'featured product' attribute,
