So, I do not have aphantasia, but I do have an impossible time recalling tastes. Kinda like how you describe your lack of memory of glass.

I can tell apart a strawberry from a pineapple, but I can't re-experience a taste later. If I want to compare two things, I need to taste them back to back. Or I need to write down what I think to compare with next time.

But I have no problem remembering things like: how crunchy or floppy the pizza was. That's not taste.
