What are some non-flashcard-style memorization techniques? I'm learning a menu as part of my job as a waiter and it feels more like trial and error. My main problem is that I can't remember the stuff at all.

I've come up with a "open answers" system that I don't really know if it can work. Let's say we have x number of things on the system, like item1, item2, item3...item(x). We also have y number of meals (which vary on the number of ingredients) and so you need to fill in the blanks, like this:

Meal 1: (underscores should be here but the "you'll never get what you see" comment system hates them)

This has the advantage of being visible which I personally like. It's also pretty simple and doesn't really require reading much beyond "fill in the blanks". It removes the disorder of "x number of things" and instead moves the question to "where should item(x) belong to?".

My only significant issue with this is that it's a trial and error thing - which I personally dislike because that's how I play chess, and most of my games end up in a loss which disappoints me and makes me think trial and error is meh, but hey I'm just one person, let's not get into typical mind fallacy here.
