Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Renders fat as it cooks, giving crisp texture and salty, savoury flavour.
- Egg
- Adds richness; when fried, the white sets while the yolk stays soft and runny.
- Parsnips
- Soften as they cook, adding tender texture and a natural sweetness.
- Bread
- Provides the toasted base that holds the other toppings.
- Butter
- Adds fat and flavour, and helps the toast brown and taste rich.
- Cream
- Adds moisture and richness that softens the savoury flavours.
The step that matters
Slice the parsnips and cook until tender. Parsnips are dense, starchy roots. Slices of even thickness cook through at the same rate; uneven pieces leave some parts firm while others turn mushy.
Swap the parsnip

Fit is the average pairing score against egg, bread, butter, cream, coffee. Candidates are from the same food group and used in at least 100 recipes.
