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):
