Magento: How do I make products available to cart ONLY if you have something else inside already?

Question

I'm trying to set up a magento shop, and basically I want certain products (add on items) only if they have the main product already in their cart. I don't want the customer to be able to purchase the add on products on their own.

How would I set that up?

To accomplish this you could Create a Bundle Product in Magento
