Why it works: Flour and almond are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Prune Souffle

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

  1. Wash the prunes and soak them in cold water for 3 to 4 hours.

  2. Place the prunes in a jar with thinly pared lemon rind and a little cold water, then cook until tender.

  3. Once cooled, remove the stones and cut the prunes into small pieces.

  4. Cream the egg yolks and sugar together, then stir in the flour.

  5. Add half of the prepared almonds, 2 teaspoons of lemon juice, and the prunes, mixing well.

  6. Whisk the egg whites to stiff peaks and gently fold half into the mixture.

  7. Pour the mixture into a buttered souffle dish or pie dish.

  8. Bake for about 15 minutes at 350°F (175°C).

  9. Top with the remaining egg whites, dredge with castor sugar, and scatter on the almonds.

  10. Return to the oven and bake for an additional 15 to 20 minutes, then serve hot.
