Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain sponge cake and its variants, relay techniques and traditions from culinary sources, describe the variants the registry aliases name, and distinguish sponge cake from chiffon cake, pound cake, genoise as a technique variant and angel food cake.

A light, airy cake leavened mainly by beaten eggs rather than chemical raising agents, the basic foam cake of many cuisines, including Japanese castella introduced by Portuguese traders in the 16th century with variants such as banana castella, bell castella and baseball-shaped yakyu castella, rolled Swiss rolls, and Vietnamese banh bo, a rice flour sponge cake; sponge cakes are the base for layered cakes and trifles.

What it is for: Food, especially desserts.

It can be explain technique; relay traditions; describe variants; distinguish related cakes.

What the second pass must settle

  • Should castella and banh bo be separate primary entries?

  • The registry entry has merged aliases naming regional variants; should they be split off?
