Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bacon Olives
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 bacon olives
Divide the sausage into six portions and roll each in a slice of bacon.
Tie each wrapped sausage with string.
Bake in a preheated oven at 400°F (200°C) for 30 minutes.
Cover each with egg and breadcrumbs and fry in hot fat.
Make the sauce
Melt the butter in a pan.
Fry the onion and carrot in the melted butter until soft.
Brown some flour in the pan.
Add vinegar to the pan and let it evaporate.
Stir in the stock and ketchup.
Bring the sauce to a boil while stirring continuously.
Serve
Strain the sauce over the bacon olives before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Streaky bacon
- Wraps the sausage, adding salty, smoky flavour and fat that bastes the meat as it cooks.
- Sausage
- Forms the filling, providing the savoury meat that the bacon wraps around.
- Egg
- Acts as a binder so the breadcrumbs stick to the outside of each roll.
- Breadcrumbs
- Form a crisp, golden coating when fried in hot fat.
- Onion and carrot
- Build the sauce's aromatic sweetness and body as they soften in butter.
- Vinegar
- Adds acidity that sharpens the sauce, and evaporating it mellows the sharp edge.
The step that matters
Frying the breadcrumbed bacon olives. The egg and breadcrumb coating must be fully set and the fat hot enough to brown quickly; otherwise the coating absorbs grease, turns soggy and can fall off the roll.
