"Help me decide" plugin for customers

First, we’re getting ready to build a new site using WordPress so I have no reference for our current site that would apply for reference.

I’m looking for a plugin that would help customers decide which chocolates they want. The individual chocolates are not products on the website (only boxes) so the standard filtering methods won’t work here. Ideally, it would be a page they go to where they start by picking a flavor like caramel, nut, fruit, liquor, etc. The plugin would then narrow down all the results to individual chocolates that have that flavor. They continue in this manor with a second flavor which narrows the results again.

For example: First flavor choice is caramel. All chocolates in our lineup with caramel are shown. Second flavor choice is nuts. All chocolates with both caramel and nuts are shown. In the end, they’ll have a result page showing them the exact chocolates they should purchase based on their flavor preferences. They can use this to hand-pick chocolates in the store at a later time or be directed on the website to which boxes of chocolates contain those individual chocolates.

I’ve tried several ways of searching for something like this but haven’t found anything remotely close to what I want. Your help would be greatly appreciated!
