If you’re looking for a frosting that’s universally loved and has truly stood the test of time, look no further than Seven Minute Frosting. Dating back to the early 1900s, there’s just no match for this light and fluffy marshmallow-like stuff. In texture and taste, no other frosting out there is quite like it. And as a frosting that’s cooked on the stovetop, the preparation is a little different from most too. (But don’t let that fool you into thinking that it’s difficult. Your grandma could handle it and you can too.)
Seven Minute Frosting is cooked in a double boiler on the stove, though if you don’t have a double boiler, a heat-proof bowl placed over a pan of simmering water works just fine. You combine all your ingredients – sugar, water, egg whites, cream of tartar, and salt – in a bowl and beat it with an electric mixer for just thirty seconds. Then you place the bowl over a pan of simmering water (but not touching the water or it will cook too fast) and continue beating for – you guessed it – seven minutes.
