  • 2 Tablespoons Dry Mustard Powder
  • 1/4 cup Sugar

  • 1 tablespoon butter
  • Pinch of Salt
  • (Slider recipe
  1. Use a double boiler (see notes for option to make your own)
  2. In the bottom pan of a double boiler bring water to a boil.
  3. While waiting for water to boil, in the top pan (which is not on top of water yet, mix all ingredients until all combined.
  4. Once water is boiling, reduce heat to medium and place top pan over boiling water. Stir constantly until the ingredients thicken to slightly more thick than a pancake batter. About 15 minutes.
  5. It is very important not to quit stirring or to up the heat to get the sauce to thicken more quickly.
  6. Failure to do either of those things will likely result in a curdled egg and a very gritty texture. It takes a bit to make this sauce, but it is worth it.
  7. Sauce can be served warm or cold depending on your preference.
  8. Store in an airtight container in the refrigerator. Sauce keeps for about 10 days.
Recipe Notes

If you don't have a double boiler you can use a 2 pans to create your own. Use one large pan and one smaller pan that will nest inside of each other. I also have used a metal bowl that I could sit atop the bottom pan. Just be careful as the bowl is really hot so use caution and heating pads when trying to remove or handle the bowl.
