Home hacks using cornstarch you probably didn't know! | DIY with Hometalk

Such a simple hack… but SO effective! “The magic in cornstarch is its ability to absorb moisture.” And I figured - why not use that to fix cake condensation once and for all? If your cakes tend to get sticky or sweaty after refrigeration, try this: Lightly spray cornstarch (aka cornflour) over your buttercream, ganache, or whipped cream cakes before chilling. It even works on colored cakes, leaving a slightly velvety, matte finish! Comment ‘Amazon’ if you’d like the link to the spray tool I use.
