My croquettes worked fine (though this was my second try too, the first went in the trash because I forgot all about them, as did another poster) but my kids HATED them. I thought they tasted a lot like falafel too. I think maybe the trick is hot enough oil to cook them together right away and also mashing the beans more. Mine second batch worked better after I processed them into an almost hummus like consistency.
I am really suprised to see all the issues people have been having with the croquettes :( I actually added about 1/4 cup shoyu (instead of the 1 tablespoon) and I also added about 1 1/2 tablespoons of shallot. I added cilantro and parsley (not just one or the other). The last thing I did different was add a clove of garlic. I soaked the black eyed peas overnight and blended everything in the food processor (you really need one). They were so yum!!! Even my husband loved them and he is soooo picky! I can't tell you how great they tasted! Give it another shot...great superbowl appetizer I think!
