I needed to make more than 2 tuna cakes, so I doubled everything and I was pretty generous with the mayo. As a result, I had trouble with the part where you press the cakes into the extra pork rinds. Solution: add the extra pork rinds to the mixture. I did have a bit of trouble with them holding together, but I found that the batter that sat while the first batch was cooking held together better. This made a lot of tuna cakes, and I could easily have gotten away with 3 cans of tuna and then improvised about the egg. I found these were very tasty and helped fill the void left by my favorite tuna cakes Tuna Patties Burgers Cakes.....something like that. I will make these again. Thank you Artboy34.
