As I've learned, "shelf stable" in the hot sauce world does not mean, "can sit in a sealed container unrefrigerated until opened", it means "can be open and left on a table without refrigeration for prolonged and unknown periods of time."Can you elaborate? I think Secret Aardvark and Formosa have oil yet they are shelf stable
Secret Aardvark recommends refrigeration after opening and consumption within 3 months. Similarly, Formosa states that after opening, their hot sauce must be stored in a fridge.
