Why it works: Arrowroot and lemon 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 ↓
Arrowroot Souffl^
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.
Make the custard base
Boil the milk with the lemon rind, stirring to prevent burning.
Mix the arrowroot with a little cold milk to form a smooth cream.
Pour the arrowroot mixture into the boiling milk and return to the saucepan.
Boil for 2 minutes, then remove from heat.
Stir in the sugar and egg yolks.
Bake and serve
Whisk the egg whites until stiff and gently fold them into the mixture.
Pour into a well‑greased pie dish or ramequin cases.
Bake in a moderate oven at 350°F (175°C) for 10 to 15 minutes.
Dust with sugar and serve hot.

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
- Eggs
- Egg whites whisked to stiff peaks trap air, lifting the soufflé as it bakes and sets.
- Arrowroot
- Starch that thickens the milk into a smooth base that holds the whipped whites.
- Milk
- Forms the liquid base of the custard that the arrowroot thickens.
- Sugar
- Sweetens the base and adds a light browning and finish on the surface.
The step that matters
Folding in the egg whites. Whites must be whisked until stiff and folded gently. Stirring or deflating them loses the trapped air, so the soufflé rises less and turns dense.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, sugar, lemon, egg):
- Asparagusfits about as well
- Arrowrootthe original
- Sweet potatofits about as well
- Capsicumfits about as well
Fit is the average pairing score against milk, sugar, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
