How to Make My Mum's Salmon Mornay

Melt 50g butter in a medium saucepan over medium heat. Whisk in 50g flour, 1 tsp salt, and ½ tsp black pepper. Cook for 1 minute, stirring constantly, until a smooth paste forms (roux).
Gradually whisk in 500ml milk. Bring to a simmer, stirring continuously, until the sauce thickens. Stir in 250g cooked salmon (flaked), 100g grated Gruyère cheese, and 50g grated Parmesan cheese.
Pour the salmon mixture into a greased ovenproof casserole dish. In a small bowl, combine 2 tbsp melted butter with 50g breadcrumbs. Sprinkle evenly over the top of the mornay.
Bake in a preheated moderate oven (180°C/350°F) for 25-30 minutes, or until the mornay is bubbly and the breadcrumbs are golden brown and crispy.
Serve immediately. Delicious served with steamed rice, roasted vegetables, or a fresh green salad.
