Add the mustard flour, sugar, distilled white vinegar, hot sauce, xanthan gum, modified food starch, minced onion, and garlic powder to a blender.
Blend the items until they are well combined and smooth.
Stirring continually, cook the ingredients in a saucepan over medium heat.
Lower the heat to low and whisk the sauce until it thickens when it starts to simmer.
Beat the eggs in another basin.
To keep the beaten eggs from curdling, slowly pour them into the sauce while whisking continuously.
Simmer for a further two to three minutes, or until the sauce becomes smooth and thick.
Before coating the chicken wings, let the sauce cool.
