Top up the blender to the 700 mls mark with water and blend until smooth (you want 700mls total liquid)
Tip the blender contents into the large bowl of beans & mushrooms
Using a wooden spoon, mix together all the ingredients in the bowl until combined.
Let this rest for 45 minutes. This allows the gluten from the Vital Wheat Gluten to hydrate and start to form the burger structure.
Once the mixture is rested, give it another mix, to be sure everything is combined. For a firmer more bouncy burger, keep mixing for 2-3 minutes. This creates the 'gluten' strands.
Preheat your oven to 180℃/356℉
Shape the burgers (will make 12 large burgers approx) and place on oven trays
Bake for half hour in the oven.
Allow your burgers to cool.
You can now finish the burgers off. Pan fry, Grill or BBQ the burgers as desired! A little olive oil on the outside of the burgers will help create the delicious caramelisation and make them full of extra flavour!
Notes
These burgers freeze really well! Just pull out the ones you need to cook on the day!
