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 ↓
Snow Flake Toast
Ingredients
Directions
Make the sauce
Heat the milk, cream, and salt in a pot until boiling.
In a small bowl, mix the flour with a little cold milk until smooth.
Add the flour mixture to the boiling milk to thicken it.
Finish and serve
Beat the egg whites until stiff peaks form.
Pour a cup of the hot sauce over the beaten egg whites, stirring constantly.
Combine the egg mixture with the remaining sauce and keep hot without boiling.
Moisten the slices of zwieback or toast with milk or hot water before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the sauce and adds creamy, milky flavour.
- Cream
- Adds richness and body to the sauce through its fat content.
- Flour
- Thickens the hot milk into a smooth sauce as its starch swells when heated.
- Egg whites
- Whipped to stiff peaks, they give the sauce a light, airy, foamy texture.
The step that matters
Combining the egg whites with the hot sauce. Pouring the sauce in while stirring constantly tempers the egg whites gently, so they blend smoothly instead of deflating. Keeping the mixture hot without boiling avoids curdling and collapse.
