Me? Oh gosh...
I think I'd taste like oil paint, graphite, or paper. Paper has a distinct paper, and starched clean sheets have a certain sweetness. It' odd, and only really there if you know what to look for, but... that's exactly it. Who eats paper? Well, news for you: I did once, and I liked it a little too much.
Oil paint is oily, of course, and kind of dry-tasting too. But it's almost... tropical. This is the girl who thoughts most farts smelled like popcorn for years. Go with it.
Aaand graphite? It's a bit bitter, but... *bites tip off pencil* Not really. It's mostly flavorless until you swallow it, when a flavor comes forth... a clear something, like spearmint. It's always cool-tasting, but only then do you really notice it. Reminds me of mint, crossed with cocoa powder, crossed with icy coffee. Not blended, but all those traits sort of mashed together to create a single flavor. It's also a bit smoky, like pork.
Probably paper. Maybe papyrus... but only when I'm older.
