Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cracker Toast
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 the crackers
Split the Boston crackers in half.
Place a small piece of butter in the center of each cracker.
Heat the crackers in a 400°F (200°C) oven until crisp.
Make the gravy
In a saucepan, combine the milk and cream.
Thicken the mixture with flour, stirring until smooth.
Add the butter just before serving.
Serve
Serve the toasted crackers with the milk gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boston crackers
- Form the crisp base that holds the butter and the gravy.
- Butter
- Adds fat and richness, carrying flavor and a smooth finish.
- Milk
- Provides the liquid that forms the body of the gravy.
- Cream
- Adds fat that makes the gravy richer and silkier.
- Flour
- Starch that thickens the liquid into a smooth gravy.
The step that matters
Thicken the mixture with flour, stirring until smooth.. Flour clumps when dropped into liquid. Stirring disperses the starch granules so they hydrate evenly and thicken the gravy smoothly instead of forming lumps.
“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.
