Plum Tart

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.

Prepare

  1. Line the edge of a tart dish with puff pastry or short crust pastry.

  2. Fill the dish with plums and sprinkle a little moist sugar over them, adjusting the amount based on the plums' quality.

Bake and glaze

  1. Cover the dish with pastry and bake in a moderate oven at 350°F (175°C).

  2. For a glazed finish, remove the tart from the oven before it is fully done.

  3. Brush the tart with whisked egg white and sprinkle with finely sifted sugar.

  4. Add a few drops of water and return the tart to the oven to set the glaze.

  5. Alternatively, brush the tart with cold water and sprinkle with white sugar before baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Plums
Provide the fruit filling and its juices, which soften and sweeten during baking.
Moist sugar
Sweetens the plums and draws out some of their juice.
Egg white
Brushed on top, it forms a glossy, lightly set glaze.
Puff pastry or short crust pastry
Forms the tart case and top crust, providing structure and flaky or crisp texture.

The step that matters

Removing the tart before it is fully done. For a glazed finish, the tart leaves the oven early so the egg white glaze can be applied and set without over-browning or drying the fruit. Pulling it too late can leave the glaze dull and the pastry overcooked.

Swap the plum

How well each one fits the dish's main ingredients (sugar, egg):

  4. Plumthe original

Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
