Why it works: Roe and egg work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 243 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Bloater Toast
Ingredients
Directions
Prepare the fish
Remove the roes from the bloaters.
Grill the herrings, then remove the skin and bones.
Chop the fish and rub it through a fine sieve.
Make the fish mixture
Heat 2 oz of butter in a small saucepan, add the fish.
When hot, stir in the egg and season to taste, cooking until thickened.
Fry the roes and serve
Divide the roes into 8 pieces and fry them in the remaining butter.
Spread the fish mixture on the toast, top with the fried roes, and serve hot.

What each ingredient does
- Bloaters
- Provide the main flavour and the soft roes that are fried as a topping.
- Butter
- Adds richness and carries flavour when cooking the fish and frying the roes.
- Egg
- Thickens the warm fish mixture as it cooks, giving it a spreadable texture.
The step that matters
Stirring in the egg. Egg proteins set when heated, so the mixture thickens only gently over low heat. If it gets too hot, the egg can scramble and the spread turns grainy instead of smooth.
