Place the crab meat in a large mixing bowl and carefully pick through for shells, then set aside.
Melt the butter in a medium skillet over medium-high heat.
Add the onion, poblano, garlic, salt, chili powder, black pepper, and cayenne and cook, stirring, until the veggies are soft - about 4 minutes.
Transfer the veggie mixture to a mixing bowl and set aside to cool for about 15 minutes.
In a large bowl, gently mix together the crab, cooled vegetable mixture, egg, mayonnaise, mustard, hot sauce, scallions, parsley, lemon juice, and ⅓ cup of the breadcrumbs.
Using a 1-cup measuring cup, form the mixture into cakes, packing gently; they should resemble hockey pucks (in size) - about 2 inches thick.
Cover the cakes and chill for 30 minutes, or overnight (covered with plastic wrap).
When you are ready to cook the crab cakes, place the remaining breadcrumbs on a plate.
Dredge both sides of each cake in the crumbs, shaking off the excess.
Heat 2 tablespoons of vegetable oil in a large skillet over medium-high heat.
When the oil is hot, but not smoking, fry the crab cakes for 4 to 5 minutes on each side, until golden brown.
Don't overcrowd the pan - fry in batches if necessary, adding more oil if needed.
Serve immediately - with Jalapeno Remoulade!
Whisk together all the ingredients in a mixing bowl.
Cover and place in the fridge until needed...or for at least 30 minutes.
