How to Cut a Cake at a Picnic Without a Knife | Eater

"Run by baker Nicola Collie, this California microbakery is skeptical of the wineglass cutting hack because it compresses cake and frosting, changes the intended order in which layers are eaten, and obscures the precise, defined slices she values given the craft behind cake-making. Collie prefers the dental-floss method—using a long piece of unscented floss held taut and wiggled through the cake like a cheese wire—to produce clean wedge or square pieces, and she recommends keeping floss handy for picnics; she also notes that cutting a round cake into a grid will maximize the number of servings." - Bettina Makalintal
