Rhubarb Tart

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Remove the leaves and skins from the rhubarb.

  2. Cut the stalks into 1‑inch pieces.

  3. Optionally, stew the rhubarb before making the tart to allow for more filling.

Assemble and bake

  1. Fill the dish high in the center with rhubarb, add sugar and lemon rind, and pour in the water.

  2. Cover the dish and bake at 400°F (200°C) for 30 minutes.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: acetic acid (sour, vinegar).

    Shared aroma: 1-penten-3-one (fish, pungent).

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Rhubarb
Forms the tart's filling and gives it a tart, fibrous body that softens as it bakes.
Sugar
Sweetens the rhubarb and balances its sharp acidity.
Lemon rind
Adds a bright citrus aroma from the oils in its zest.

The step that matters

Fill the dish high in the center. Rhubarb shrinks and releases moisture as it cooks, so a low fill can leave a thin, sunken tart. Mounding it higher allows for that collapse.

Swap the rhubarb

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

  1. Cinnamonfits better
  2. Gingerfits better
  3. Marjoramfits better
  4. Rhubarbthe original

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