Why it works: Butter and parmesan cheese are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,163 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Fillets Op Bloaters on Toast
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Skin, split, and bone the bloaters, then cut them into neat fillets.
Brush the fillets with oiled butter.
Broil the fillets over high heat.
Assemble on toast
Prepare the toast.
Butter the toast well.
Sprinkle the toast with grated Parmesan cheese.
Place one fillet on each piece of toast.
Bake in a hot oven at 400°F (200°C) for a few minutes.
Garnish and serve
Garnish with parsley.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bloaters
- Provide the main fish fillets, which carry the dish's flavour and form its centrepiece.
- Butter
- Adds richness and carries flavour, and helps the fillets and toast brown lightly.
- Parmesan cheese
- Melts and browns on the toast, adding savoury flavour and a crisp, golden topping.
The step that matters
Broiling the fillets over high heat. High heat cooks the thin fillets quickly and browns the surface before they dry out. Too long under the heat makes the fish tough and dry, so watch them closely.
