One recipe I found listed tis as a substitute for savorex:
Savorex and Vegex are both gluten-free products. However, it's always best to check the packaging or the manufacturer's website for the most accurate and up-to-date information, as formulations can change. If you have celiac disease or severe gluten sensitivity, ensure that there are no cross-contamination risks.
A good substitute for Vegemite is Marmite, as both spread have a similar savory, umami flavor profile. Nutritional yeast can also be used for a similar taste, especially when mixed with a bit of water to create a spreadable consistency. Additionally, soy sauce or miso paste can provide a savory kick in recipes that call for Vegemite.
