We had a Brazilian store near us for about 6 months. Bought some there. It was like 1/2lb cryovac and it was like $15. I like the ham hocks better to tell you the truth and use polish kielbasa for the sausage, It actually tastes better with pork IMO.
The topping is called Farofa, its a yucca meal, if you can find it. My mom gets it sent in from relatives of my dads so she always has it, ( and I steal some quite often) You fry up some bacon sliced into small pieces, then when rendered save a bit of fat and pour the yucca meal in with some parsley and fry it up a while. This adds a nice crispy bacon texture to it.
You dont even need a recipe. Just get a large pot, 1lb black beans soaked over night. Fry up bacon, when rendered add a large onion, garlic and bay leaves. Then add beans, smoked ham hocks/shanks and sausage, cover with water plus a few inches and bring to boil, add a few bullion cubes or use stock in place of the water then simmer for hours until the ham hocks/shanks start falling apart. I usually do this on sunday, watch football and the mouths start watering in the evening. Then just pick the hocks apart, keep the meat, throw skin and bones away. Sometimes we add ham in there as well if we got some frozen from easter or some shit.
