The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. Line a flat baking sheet with buttered paper.

Make and bake

  1. Mix the grated cocoa-nut, sifted sugar, and egg whites in a bowl.

  2. Drop spoonfuls of the mixture onto the prepared baking sheet.

  3. Bake for 30 minutes.
