Ingredients
Directions
Make the base
Melt the butter in a pan over medium heat.
Add the flour and stir until combined.
Gradually stir in the milk and bring to a boil, then remove from heat.
Mould and steam
Add the chopped fish, anchovy essence, and beaten egg. Season with salt and pepper.
Pour the mixture into a buttered mold, cover with buttered paper, and steam for 30 minutes.
Serve
Turn out the mold, garnish with parsley, and serve with any fish sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the mould and gives it its flavour.
- Egg
- Binds the fish and sets when steamed, holding the mould together.
- Flour
- Thickens the milk into a sauce that gives the mixture body.
- Milk
- Forms the moist, creamy sauce base that keeps the mould tender.
- Butter
- Adds richness and carries flavour in the starting roux.
The step that matters
Bring the milk sauce to a boil before adding the fish. The flour must be fully cooked into the milk so the sauce thickens smoothly. If the base stays thin or lumpy, the mixture will not hold its shape when steamed and turned out.
