What the burger comes with: delicious smoked cheddar cheese, grilled onion, pickles
Impossible or Beyond?: Impossible
I’ll admit I was worried about the quality of this burger. See, one of the closest White Castle locations to my home state of Colorado is in Las Vegas. Which is great! But it’s inside a, umm, Best Western hotel. Sorry, a Best Western Plus Casino Royale! My apologies. So as I walked through rows of slot machines inside the decidedly old-school confines of the resort casino to get to the burger palace, I expected to find a White Castle unchanged from the ‘20s. What I saw instead was a gleaming, modern open kitchen, a spotless interior, and the best damn meatless burger in fast food. (Speaking of which, just had a great idea for a sign White Castle could hang up: “The White Castle Impossible Slider: Your Tastebuds Will Hit the Jackpot!” OK, OK, I’ll show myself out.)
It was clear from eating the Burger King Impossible Whopper that how the burger was prepared was equally as important as what was on it. This Impossible Slider came from the kitchen straight off the grill, with as juicy a patty as you’d expect from a beef burger. If you’ve ever had a White Castle slider, you know the bun is pillowy perfection, and the burger is nestled in there with smoked cheddar, grilled onions, and pickles. It doesn’t need ketchup, mustard or mayo. Everything you need is right there. The smokiness from the cheddar and the sizzling onions are a glorious pairing with the Impossible patty. The one downside is that it’s just a tiny slider, so you’re going to need to order a couple. But that's a small price to pay for the best-tasting meatless burger money can buy.
