Combine 1/4 cup yogurt, cucumber, garlic, and 1/4 teaspoon pepper in a small bowl; set yogurt mixture aside.
Combine remaining 2 tablespoons yogurt, remaining 1/4 teaspoon black pepper, 1/3 cup panko, bell pepper, onions, dill, rind, juice, salt, and egg white in a medium bowl. Gently stir in crab. Divide crab mixture into 4 equal portions (about 1/2 cup each), shaping each into a 3/4-inch-thick patty. Place remaining 1/3 cup panko in a shallow dish. Dredge patties in panko.
Heat a large skillet over medium heat. Add oil to pan; swirl to coat. Add patties; cook 3 minutes on each side or until golden. Top each bread slice with 1 lettuce leaf, 1 patty, and about 2 tablespoons reserved yogurt mixture.
These are incredible. I added a small squeeze of lemon and some dill to the tzatziki. I also used yellow pepper as that is what I had on hand, and 1 whole egg. The family devoured it. It maybe loses half a point for being a little messy. I think next time I'll serve the cake on some salad greens and have the bread on the side.
First time making Crab cakes. I thought they were absolutely delicious. My husband and I were making yummy sounds the whole time while eating them. I just noticed the double the egg yolk in the other reviews. I halved the recipe, but used the whole egg white just cause I thought it needed it, and mine did not fall apart. So apparently doubling it works. I made the sauce twice because there was simply too much garlic. I added dill to the sauce and lemon juice. I substituted mayo for the yogurt in the Crab cake (I know, I know FAT) and I think it tasted great. I thought they were light and delicate and just simply amazing. I hope that I can duplicate it next time.
This was my first time making crab cakes. They had good flavor and I liked the crunch the bread gave. I didn't have green onion, so I subbed leeks. I also added some dill and lemon to the tzatziki. As everyone else has said, they did fall apart, so more egg next time.
This was an exquisite recipe. I doubled the tzatziki recipe beacause I love it, but didn't double the pepper (that's a lot of pepper!). I wish I would have added an extra egg white as reviewed, but otherwise this was really easy and so very tasty.
