Put everything except the wheat gluten into a jug and use the stick blender to make a paste.
Put the paste and gluten in to the food processor and blitz on full power for about 1 minute until it forms a dough.
Cut the dough in to 4 equal pieces. Flatten each piece to the surface, then fold in half, work flat, fold in half the other way. Repeat this a few times and begin to form your burger shapes as you do this. The patties want a springy texture as you push your finger on the surface
Place each patty on to a piece of baking parchment and pop two per steamer tray.Steam for 30 minutes, then flip each patty over and put the lower steamer tray to the top and steam for a further 30 minutes.
Leave the patties to rest for an hour in the fridge before frying. This will let them firm up. You can fry them straight away for a softer finish.
Finish the burgers off in a frying pan with a little oil or under the grill, about 3-4 mins each side until nicely browned.
Serve in a bun with all your favourite burger accompaniments!
Notes
The burgers will keep for a few days in the fridge and freeze too, so you can keep some on hand for a quick, delicious meal anytime.
