To make the aioli, place the ingredients in the bowl of a food processor and blend until smooth. Season with salt and pepper to taste.
For the crabcakes, whisk first six ingredients together in a mixing bowl.
Drain the crab well, squeezing out excess moisture. Remove any bits of shell or cartilage. Add the crab and the panko to the bowl with the other ingredients, and fold in until well combined. Season with salt and pepper.
Form 6 equal size cakes and place them on a sheet pan. Chill for at least 30 minutes, or overnight if making ahead.
Heat a large skillet over medium high heat. Add 2 tablespoons canola oil to the pan. When the oil is hot, add the crabcakes and sear, 2-3 minutes per side. Serve immediately.
