Don't Toss Out Used Coffee Grounds When You Could Use Them To Keep Cooking Odors At Bay - Tasting Table

"We've shared tips for using coffee grounds before, and this is one of the best ones. Coffee grounds make an extremely effective natural deodorizer. You don't need to waste coffee that you would otherwise drink, either. Used coffee grounds work just as well as fresh ones, so you get double the benefit from them. If you want to use coffee grounds for a specific mess or as a general deodorizer, make sure they are dry."

"Wet coffee grounds aren't going to be effective, but they're easy enough to dry. Take the used grounds and layer them on a sheet pan. Then put them in a 250-degree oven until they're dry. Keep an eye on them so they don't burn. After that, put a spoonful or two in a bowl or jar near the source of the smell. That's all it takes."

Used coffee grounds function as an effective natural deodorizer and work as well as fresh grounds. Wet grounds are ineffective and must be dried before use. Spread used grounds on a sheet pan and dry them in a 250-degree oven, watching carefully to avoid burning. Place a spoonful or two of the dry grounds in a bowl or jar near the odor source to neutralize smells within about an hour. Brewing coffee masks odors by adding aroma, while dried grounds neutralize odor compounds via chemical interaction with odor-causing molecules.
