Today I’m showing you the Fish in Mustard Sauce Recipe.

It’s a poached redfish fillet with mashed potatoes and mustard sauce.

The warm sauce goes well with cooked seafood like cod, redfish, sole, plaice and salmon – as well as freshwater fish like pikeperch, trout, perch and carp.

You can fry or poach your fish, even freshly smoked fish goes well with warm sauce.

I’ll show you the warm mustard sauce with fish in two + one variations.

Both sauces work in less than 15 minutes.

In addition, I have added a quick recipe for cold mustard sauce:

Keywords are Graved Salmon (Gravlax), Ikea Mustard Sauce, Smoked Salmon

So you can react flexible to the situation and wish you good success and a lot of fun cooking by yourself.

2. Mustard Sauce Recipe (warm), the quick Variation

If you have to go really fast, here is the recipe mustard sauce for the fast kitchen…

Adjust the strength of the bond to your taste.

You can either boil the sauce down or add a little more cornflour.

Please be careful, the sauce does not bind until it is cooked.

This means: add cornflour, bring to the boil, check binding, add more cornflour to taste.

Important: Always mix cornflour with cold liquid, then add to warm liquid. You can also stir cold and bring to the boil. The sauce doesn’t clot!
