The cake is named after a native Uruguayan bird known for looking bulky but weighing almost nothing — exactly the light, airy texture the confectioner was aiming for.
Layers of sponge cake, dulce de leche, whipped cream, meringue bits, and peach are stacked and coated entirely in more meringue and cream. Bakeries across Paysandú sell it by the slice from glass display counters.
