I have been using this since I got my first microwave in 1984! This recipe came with the cookbook included with my Quasar microwave but added 1/8 teaspoon of white pepper and 1/8 teaspoon of dry mustard also. It just adds a little flavor, since I leave out the salt. It is so much easier than the top of the stove method.

Worked like a charm! I haven't bought any white based sauces since I started making this recipe. Thanks so much for posting this versatile, little gem!

Wonderful base recipe. I used it to make a cajun alfredo sauce by adding cajun seasonings and parmesan cheese. yum! My hubby liked even better than the original stove-top version. I look forward to trying your variations. Thanks for sharing!
