Step by step recipe

Stage 1 - 5 min.
Mornay Sauce
Prepare 500 g Bechamel sauce, or reheat it if you made it in advance.

Stage 2 - 1 min.
Mornay Sauce
Add 30 g egg yolk...

Stage 3 - 4 min.
Mornay Sauce
...and bring back to the boil, whisking constantly.

Stage 4 - 1 min.
Mornay Sauce
Add 50 g Comté cheese...

Stage 5 - 4 min.
Mornay Sauce
...and carefully whisk in.

Turn off the heat and your Mornay sauce is ready.

Note: If you need a very smooth sauce, you can give it a quick blast with a blender, or strain it through a sieve.

Stage 6
Mornay Sauce
If you're not going to use it straight away, wrap it in plastic wrap, as, like béchamel sauce, it crust quickly.
The cheese used is usually a hard one: Comté, Gruyère, Emmental, Cheddar, Parmesan, etc., but you can also use other cheeses to suit your taste, such as Roquefort, Mont d'or or Gorgonzola.

Curiously enough, in his book "Ma cuisine", Auguste Escoffier uses Parmesan and no egg yolks for his version of Mornay.

The name comes from a 19thcentury epicurean named Philippe de Mornay.

Usually to make fruit jellies or (fruit "paste"), it's like jam but you need to cook fruit pulp and sugar much longer. Unfortunately, this long cooking is bad for both vitamins and flavour. In this recipe we use a special jam gelling agent, to reduce cooking time as much as possible .
