Get a large frying pan and start heating up enough oil to fry on medium-high flame.
Coat all the beef in the xanthan gum.
Fry the beef a batch at a time, until both sides are nicely browned and crispy. Leave on paper towels after being removed from the oil.
Remove all the oil from the pan except for one tablespoon.
Mix together all the rest of the ingredients in a bowl and add in one teaspoon of xanthan gum. Then pour it into the hot frying pan.
Bring the sauce to a boil while whisking. Then keep whisking for 2 more minutes. Take off the flame and mix it in a dish with the fried beef well.
