Black beans in my opinion are the best for burger pattis as they are so flavorful. This is my favorite black bean patti recipe.
Recipe adapted from here
For the patti (for four patti)
You will need
12 oz. beans (I used half black beans and half garbanzo)
3 tbsp. yellow onion, diced
3 tbsp. red bell pepper, diced
3 tbsp. black olives, diced
1 Serrano pepper, minced
4 oz. rolled oats
1 tsp. paprika
1 tsp. dried oregano
1 tbsp. cilantro, minced
1 tbsp. cumin seeds
2 tbsp. bread crumbs
salt and black pepper to taste
If using dried beans for the patti soak them overnight and pressure cook the next day. If using canned or a carton of beans skip this step.
Bake either sourdough buns or buns made with commercial yeast like the ones below. You will need four buns for this recipe. You could use store bought buns too.
To make the patti drain the beans and transfer to a bowl. Combine with all the other ingredients. Use your hands to crush the beans a little without turning them to mush. Let the mixture sit in the refrigerator for half an hour. Prepare a ramekin by placing a rectangular piece of plastic wrap in it such that it extends beyond the sides. Divide the patti mixture into four portions. Place one portion in the ramekin over the plastic wrap and press down.
Once the patti shape is formed pull the plastic wrap to release the patti. Continue to shape the remaining three portions. Place in a refrigerator to firm up until needed. Heat a griddle pan and add a few drops of oil on it. Place one or two patti on it and brown both sides flipping over just once. Repeat for the other two.
Prepare burgers with onions, tomatoes, lettuce and anything else you like.
