Why it works: Lemon and arrowroot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 553 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Frangipan and Apple Pudding
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the custard
Boil the milk and cream with the lemon peel, cinnamon, and sugar.
Thicken the mixture with arrowroot, then remove the peel and cinnamon.
Stir in the egg yolks and let the mixture cool.
Assemble and bake
Butter a souffle dish and layer sliced apples at the bottom.
Cover the apples with apricot jam, then alternate layers of frangipane, apples, and jam until the dish is full.
Bake in a moderate oven (350°F / 175°C) for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Set the custard as it bakes and add richness and a smooth texture.
- Arrowroot
- Thickens the hot milk and cream into a smooth custard without making it cloudy.
- Milk and cream
- Form the liquid base of the custard, giving body and a rich mouthfeel.
- Apples
- Add tart fruit flavor and moisture between the custard layers.
- Apricot jam
- Adds sweetness and fruity flavor between the layers.
The step that matters
Thicken the mixture with arrowroot. Arrowroot must be fully thickened over heat before the egg yolks go in. Under-thickened custard stays runny, and boiling after the yolks are added can curdle them and spoil the smooth texture.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, cream, lemon, cinnamon, sugar, egg, butter):

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