For the mayo, roast the jalapeno pepper over an open flame to char the skin. Keep flipping to get each side, about 5-6 minutes, until the skin is nicely charred. Remove and cover with a paper towel. Cool, then rub off the charred skins. Place into a foodprocessor.
Add basil and mayo and process until smooth. Set aside.
For the salmon patties, heat a small pan to medium heat and add some oil. Add jalapeno and onion and cook about 5 minutes.
Add garlic and cook 1 more minute.
Add to a food processor.
Add raw salmon and process. Remove and set into a mixing bowl.
Add egg, panko, olive oil, cilantro, Cajun seasonings, and salt and pepper. Hand mix.
Form into 2 patties and cook in a medium-heated pan with a few splashes of olive oil. Cook about 5 minutes per side, or until cooked through.
Set onto toasted buns and top with the jalapeno-basil mayo. Serve with extra jalapeno peppers!
Notes
I love these salmon cakes! Or salmon patties. Or salmon burgers. Whatever you'd like to call them!
