Plan Check in Los Angeles is known for their insane dishes. One of the cooler innovations from the Plan Check kitchen is their "Ketchup Leather." Though it looks more like a Fruit Roll-Up than actual leather, the tangible condiment is actually solidified ketchup.
The purpose of the Ketchup Leather, according to Food Steez, is to keep the sweet red sauce from soaking into the burger bun. Upon contact with the meat patty, the perfect square of ketchup rehydrates itself.
If there's a takeaway from any of this, it's that we need more Ketchup Leather in our lives. Our burger buns have been unbearably soggy these days.
