Beef Bouillon Paste (Best Option)
1 teaspoon paste dissolved in 1/4 cup warm water per 1 cup beef brothBeef bouillon paste is a concentrated form of beef broth that contains beef extracts, salt, and seasonings, delivering a strong umami punch essential for beef burgers. It works by infusing the meat with meaty flavor without increasing moisture content significantly, which helps maintain the burger's structural integrity.
When using bouillon paste, dissolve it fully in warm water to ensure even distribution of flavor throughout the meat mixture. Be cautious with salt levels since bouillon paste is typically salty.
Compared to beef broth, this substitute intensifies the beef flavor and keeps the burger juicy but not soggy, resulting in a more flavorful and texturally balanced burger.
