Every season of Big Brother, we see contestants endure the horror of what's known as the Big Brother "slop." It kind of looks like the cold "mush" that Miss Hannigan served in the 1982 version of Annie, and we bet it tastes like it, too. The cast of Big Brother has been served slop since 2006 (before then, houseguests generally ate simple meals like peanut butter and jelly sandwiches).Fans have long since wondered what's in the slop. Is it like really bad oatmeal? Is it sawdust? Could we picture ourselves surviving off of slop for that long? (The answer to that last question is a collective "no.")What is in the 'Big Brother' slop? Here's the recipe.In 2019, Big Brother revealed what's in the infamous slop: Oats, water, unflavored whey protein, unflavored soy protein, and vitamin and mineral powder. It's flavorless and dry, but it's got all the vitamins and minerals you need. Luckily, it's not like contestants have to eat slop every single day for every single meal. It's generally reserved for punishment after not completing challenges super well. In fact, some contestants win a Slop Pass, which allows them to skip the tragic meal altogether.The alleged recipe is this: \n\n-5 cups of steel oats\n\n-1 cup unflavored whey protein isolate\n\n-1/2 cup unflavored soy protein\n\n-4 tbsp. vitamin and mineral powder\n\nYou bring 12 cups of water to a boil, add the steel cut oats, and cook for about 25-30 minutes (stirring constantly, so the oats don't get stuck to the pot). Then you add the rest of the ingredients.According to Online Big Brother, eating slop can cause weight and energy loss, emotional instability, gas and bloating, and even allergies (during Season 9, Allison, who's a diabetic, had to go to the hospital after eating slop — after this happened, the show producers let the contestants add some sugar if they want in order to prevent an incident like this from happening again). You can technically add other ingredients, so some BB contestants have gotten pretty creative.The approved slop add-ons, according to Online Big Brother, are "balsamic vinegar, olive oil, vegetable oil, hot sauce, ketchup, BBQ sauce, mayonnaise, mustard, pickles, relish, salsa, soy sauce, steak sauce, Worcestershire sauce, honey, black pepper, garlic salt, crushed red pepper, salt, vanilla, basil, bay leaves, cinnamon, leaf oregano, paprika, parsley, rosemary, brown sugar, artificial sweetener, powdered creamer, white sugar, tea and protein powderThere are technically different ways to consume slop, too. You can make bunless burgers, slop "meat" balls (if you add extra protein powder, you can apparently roll the slop into balls), slopcakes, and breakfast slop. Slop is certainly here to stay, and we couldn't imagine Big Brother swapping it out with anything more iconic. In fact, over the years, people have recreated the BB slop for fun, and the videos are pretty funny.Judging on the reactions from these videos, slop seems just as disgusting in real life as it is on Big Brother (which is also "real life," but, you get what we mean).Watch Big Brother every Wednesday and Sunday at 8 p.m. EST and on Thursdays, you can catch it at 9 p.m. EST. on CBS.
