[BarbaPeru]

Hi, I'm typesetting a recipes book (for hobby), in this book every recipe is a section, I have and index containing the ingredients of every recipe in this form:

water, 4-7
salt, 4, 6, 8
sugar, 5, ,8-10

I want the name of the recipe (section) near every appearance:

water,
home made pasta, 4
something else, 5
another recipe, 6
salt,
very ugly cake, 4
not edible yogurt, 6

and so on.

How I can achieve this?

Thanks, BarbaPeru.
