Elizabeth Douglas, The cake and biscuit book (1903)
“ Set the cake in the middle of the oven and do not move it until it has risen its full height, which will take about half the time in which it is baked. For the first quarter of an hour it is not necessary to look at the cake unless there is a fear that the oven is too hot. Afterwards do so occasionally, opening and shutting the oven door very gently and never taking the cake out. After it has fully risen, the cake can be turned round if it is baking quicker on one side than the other. ”
