So I've been curious about the Impossible Slider (https://impossiblefoods.com) for a while now, although it wasn't available in my area (I think some places in Columbus have them now).
Then I found out White Castle took the Impossible Sliders nationwide, so sure, why not.
Texture: Maybe a bit soft, but it's White Castle. Not bad, though.
Taste: ...it tastes like you took beef, but replaced whatever made it taste umami with soy or mushrooms or something. Weird, but not bad.
