Why it works: Flour and pepper are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 50,459 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Preparation of Bacon
Ingredients
Directions
Cook the bacon
Cook the bacon slices in a skillet until crispy.
Remove the bacon and set aside, leaving the fat in the skillet.
Cook the liver and make the sauce
Add the liver to the skillet and cook until browned on all sides.
Sprinkle the flour over the liver and stir to coat.
Gradually add boiling water, stirring until the mixture thickens.
Season with salt and pepper, and serve with the crispy bacon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- The main protein, which browns in the bacon fat and forms the centre of the dish.
- Bacon
- Adds savoury, salty flavour and crisp texture, with its rendered fat carrying flavour into the pan.
- Flour
- Thickens the pan juices into a smooth gravy when combined with the boiling water.
The step that matters
Add the boiling water gradually. Flour must be coated and then whisked into hot liquid slowly so starch granules swell evenly; adding it all at once or cold causes lumps and a thin or uneven gravy.
“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.
