Why it works: Mustard and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chicken Sandwiches
Ingredients
Directions
Prepare the filling
Chop the white meat of the cooked chicken and a small portion of the dark meat.
In a saucepan, melt the butter, then stir in the flour and mustard.
Gradually mix in the water and milk, then add the celery salt and lemon juice.
Combine the sauce with the chopped chicken meat.
Assemble
Spread the mixture between thin slices of buttered bread and cut into fancy shapes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the melted butter and water-milk mixture into a smooth sauce.
- Butter
- Adds richness and fat to the sauce and gives flavour to the bread.
- Milk
- Adds moisture and creaminess to the sauce.
- Cooked chicken
- Provides the main filling, giving the sandwich its bulk and savoury flavour.
The step that matters
Gradually mix in the water and milk. Adding liquid slowly while stirring keeps flour from forming lumps, so the flour-butter base blends into a smooth, even sauce.
