Lemon Pie

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Slice the lemon very thin.

  2. Lay the sliced lemon in a pie crust.

  3. Sprinkle the flour and sugar over the lemon slices.

  4. Fill the pie nearly full with water.

Bake

  1. Cover the pie.

  2. Bake in a 300°F (150°C) oven for nearly an hour.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
