Why it works: Milk and flour 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 ↓
Yorkshire Pudding
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 batter
Beat the eggs together until light.
Add salt and milk.
Pour in the flour and mix until smooth.
Add the remaining milk and mix well.
Bake and serve
Remove the roast beef from the roasting pan and pour off the gravy, leaving some drippings.
Pour the batter into the pan.
Bake in a 400°F (200°C) oven for 20 minutes or more, depending on size.
Serve under the roast beef or cut into pieces and serve around the beef.

Milk and flour 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
- Beaten eggs give the batter structure so it rises and sets as it bakes.
- Flour
- Flour forms the gluten network that gives the pudding its set structure.
- Milk
- Milk adds moisture and helps the batter bake up tender and custardy.
The step that matters
Pour the batter into the hot pan. The pan with drippings must be very hot before the batter goes in. The sudden heat creates steam that lifts the batter and produces the high rise.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
