Appreciation post: my grandma watched me frost a cake and quietly handed me a butter knife
I was 22 and trying to spread cold buttercream with a spatula at her kitchen table in Tulsa, and it was tearing up the crumb like sawdust. She didn't say a word, just slid me a plain butter knife she'd warmed under the tap and tapped the bowl twice. Turns out a warm blade glides and a cold spatula rips, so what's your go-to tool for smoothing frosting without wrecking the cake?
