6 cups Beef Broth or Beef Bone Broth (fat removed)
1 1/2tablespoons Shrimp Powder or 1/3 teaspoon Anchovy Paste (I used this paste- amazon link)
2 1/2 tablespoons White Vinegar (optional)
Instructions
Add the beef broth, white vinegar, and shrimp powder (or anchovy paste) to a slow cooker. Leave the lid partially open so liquid can evaporate.
Cook on high for several hours. Then turn it to low and leave it to evaporate for a few more hours (or overnight). The liquids should reduce by about 70%. Store in a glass bottle in the refrigerator.
If, after refrigerating, the sauce is too thick, place the bottle in warm water. Enjoy! For longer term storage, once a week, pour the whole bottle into a pan and bring to a boil (for 40-60 seconds). Meanwhile, wash and clean the bottle. Pour the sauce back into the bottle and return to the fridge.
