Useful for this recipe

This is what you do


  1. Mix the flour, sugar, salt and mustard-powder in a micro safe bowl, stir in the milk

  2. Boil the sauce on full effect for about 3 minutes without lid. Give it a heavy stir every 30 sec.

  3. The sauce can easily boil over and the stirring will help avoid this.

  4. It also helps circulate the flour more evenly so you don’t get any lumps in your sauce.

  5. Take the sauce out of the microwave and stir in some “air” to make sure it isn’t still boiling.

  6. Mix in the egg yolk and then warm it up again for 30 sec – 1 min. On full effect

  7. “Season” to taste with vinegar. The sauce should be slightly sweet-sour

  8. Stir in the butter and you are ready to serve.


Notes; This Mustard Sauce goes very well with grilled pork-chops, smoked sausages and chicken

    Hi Marith- I am a big fan of mustard and really enjoyed your post. Directions were easy to follow and again I like to be able to follow along with the beautiful images. I was thinking of replicating this with just a touch of cinnamon- Can’t wait to try this out!
