A couple who celebrated their 60th wedding anniversary last week have revealed one secret to keeping their marriage from getting stale: eating cake that is very, very much so.

Ann and Ken Fredericks of Satellite Beach, Florida, celebrate their anniversary by eating a bite from their wedding cake every year — the remains of which they’re now keeping covered in plastic wrap inside a metal coffee can, Florida Today reports.

But they don’t store it inside a refrigerator or freezer. The cake’s actually sitting inside a closet at room temperature.

Ann Fredericks, 81, said their children are “appalled” they’re still eating the decades-old dessert, but said the dark fruit cake will keep indefinitely. They pour brandy over the cake to moisten it before digging in, and usually break open a bottle of champagne to go with it, she said.

“Believe me, it’s quite tasty, as long as it’s got enough brandy on it. And it’s never made us sick,” she told Florida Today.

She did tell ABC News that “it’s a little dry.”
