1. Ensure beans are truly tender before pureeing; undercooked beans will result in a grainy texture. 2. Add salt only after the ham hocks have cooked and been removed, as they impart significant salinity. Taste and adjust carefully. 3. For varying textures, you can control how much soup is pureed. An immersion blender can be used directly in the pot for easier cleanup. 4. Take care to remove all bones, skin, and excess fat from the ham hocks before adding the meat back. 5. The butter pat garnish adds richness, but consider a drizzle of good olive oil, fresh chopped parsley, or even crispy bacon bits for alternative finishing touches.
