Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring roe
- Provides the rich, savoury filling inside each bacon roll.
- Bacon
- Wraps the filling and adds fat and savoury flavour as it fries.
- Frying batter
- Forms a crisp, golden coating around the rolls when fried.
- Tomato
- Adds moisture and a light acidity that balances the rich filling.
The step that matters
Fry in hot fat until golden brown. Hot fat sets the batter quickly, so it crisps before it can soak up grease. Frying too cool makes the coating heavy and greasy, and the bacon and roe may not cook through.
Swap the tomato
How well each one fits the dish's main ingredients (roe, parsley, pepper):
- Carrotfits better
- Shallotfits better
- Potatofits better
- Tomatothe original
Fit is the average pairing score against roe, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
