Why it works: Lettuce and beetroot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 678 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

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 bread
Preheat the oven to 400°F (200°C).
Cut bread into desired shapes: heart, round, or square.
Butter a baking tray.
Crisp the bread slices in the oven.
Let the crisped bread cool on a dish.
Assemble the canapés
Spread a layer of green butter on each piece of bread.
Top the bread with prawn or lobster meat. Mix the meat with butter.
Season the mixture with Nepal pepper. Smooth the mixture with a knife.
Add a lettuce leaf on top.
Place a shaped piece of beetroot on each canape.
Drizzle a spoonful of mayonnaise sauce over each canape. Sprinkle with chopped olives or capers if desired.
Chill the canapes on ice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Prawn or lobster meat
- Forms the main savoury topping and provides the core flavour of each canapé.
- Green butter
- Adds richness and fat that carries flavour and helps the topping adhere to the crisp bread.
- Bread slices
- Provides a crisp, sturdy base that holds the topping without going soft.
- Mayonnaise sauce
- Adds creamy moisture and richness over the topping.
The step that matters
Crisping the bread. Bread must be fully dry and crisp before topping; if it is under-baked it stays soft and soggy under moist toppings, and it should cool before assembly so steam does not wilt it.
Swap the beetroot
How well each one fits the dish's main ingredients (bread, butter, lobster, pepper, lettuce, sauce, olive):
- Capsicumfits better

- Tomatofits better
- Beetrootthe original
Fit is the average pairing score against bread, butter, lobster, pepper, lettuce, sauce, olive. Candidates are from the same food group and used in at least 100 recipes.
