Place of Origin. Moses Lake, Washington. Every August, the Grant County Fair returns to Moses Lake, Washington. With it comes the fair's most well-known food: Spaceburgers. Two slices of white bread go in a special sandwich-making machine that seals inside a mixture of seasoned ground beef, sauce, and shredded lettuce.

Texas burger ingredients: 1 teaspoon of chili powder. 1 teaspoon of kosher salt. 1 1/2 cups of your favorite barbecue sauce. 2 cups of sharp cheddar cheese, smoked and shredded. 6 onion hamburger buns.

Color is not a reliable indicator of doneness, so the only way to be sure that hamburgers are cooked safely is to use a food thermometer. Ground beef is safe when cooked to an internal temperature of 160 °F as measured with a food thermometer.

And since any piece of meat is only as cooked as its least cooked part, you need to cook the ground beef to 160°F (71°C) to ensure it is safe to eat. Of course, with carryover cooking, that means you'll want to pull your burgers at 155°F (68°C) to achieve the best temp possible.
