Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mock Cream Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the mock cream
Beat the eggs well in a bowl.
Add the flour and mix until smooth, then stir the mixture into the boiling milk.
Add salt and sugar to taste, and flavor with essence of lemon.
Stir continuously while boiling until smooth.
Bake and serve
Line pie plates with puff pastry and bake in a 400°F (200°C) oven.
Once baked, fill the crusts with the mock cream.
Sprinkle powdered sugar on top and return to the oven to brown.
Bake until the top is a fine color.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Thicken the milk mixture as they set and give the cream its rich body.
- Flour
- Thickens the cream by swelling with heat, giving it a smooth, spreadable texture.
- Milk
- Forms the liquid base of the cream, which thickens as it cooks.
- Puff pastry
- Forms the crisp, flaky pie crust that holds the cream.
- Powdered sugar
- Dissolves on top of the pie and caramelizes lightly to brown the surface.
The step that matters
Stir continuously while boiling until smooth. Egg and flour mixtures can scorch on the bottom or form lumps if left unattended. Constant stirring keeps heat even and starch and egg proteins blended into a smooth, thick cream.

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