The recipe I want to make calls for 3lb pork shoulder, either left whole or cut in cubes. They get smothered in chile sauce and cooked slowly in the oven. Boyfriend could only find pork shoulder blade steaks at the store, so he bought two which together weigh roughly 3lbs. Should I use them? If so, leave them whole or cut into cubes? If not, any advice about how to adapt the recipe or what to use them for instead? Thank you!
