Black beanburger with a sauce of fermented black beans

Are you looking to eat less meat and more plant based, but are you craving a meaty burger with sauce dripping from the bun now and then? Then I have something for you. This black bean burger is protein packed and full of goodness. Black fermented beans give the burger a meaty flavour that you will love. You can make it as messy as you like with tomato ketchup and fried shiitake mushrooms and I could also imagine some sweet and sour red onions would be happy to join the party.

To serve

  1. Boil the Puy lentils for about 15 to 20 minutes until they are cooked.
  2. Start by making the fermented black bean sauce. Process the fermented black beans, garlic, chili (without seeds), rice vinegar and soysauce into a paste. Bring 200 ml of stoch to the boil and add the paste to it.
  3. Stir the cornflour in the cold water and when it is smooth you can add this to the boiling sauce. Mix well and when the sauce thickens you can set it aside.
  4. Boil the field peas for about 4 minutes.
  5. Add the black beans and the peas to a food processor and mix them into a puree.
  6. Put the onion, cooked lentils and oatmeal into a bowl. Add about 130 grams of the fermented black bean sauce and then add the puree of black beans and peas. Mix with a spoon until well combined.
  7. Divide the mixture into 6 portions and make burger patties of them wth your hands.
  8. 'Bread' them using the sesame seeds and fry them in some oil and butter until the sesame seeds start to caramelise.
  9. Also fry the shiitake mushrooms.
  10. Now it is time to fix the burger the way you like it, with a bun, some lettuce, tomato ketchup and fried shiitake mushrooms, and then take a good bite...
