great recipe. I would add a couple of things. One, adding sugar cuts the bitterness. Don't add more than a couple of tsp because you don't want the greens to taste sweet. Two, I add a couple of tablespoons of vinegar. I use rice vinegar but I don't think it makes a difference. Three, experiment with seasonings. I add garlic, onion powder, season salt, and others that I have experimented with over the years. The red pepper flakes are definitely a must but should be added maybe a half hour before cooking is complete. Last, try experimenting with different smoked meats. I've found that a combination of smoked turkey and smoked pork takes my greens over the edge. I have sliced fresh tomato handy for folks to cut up in their greens and a little pepper soaked vinegar. Been making greens this way for years. Never had one complaint and I am always asked to cook the greens at every occasion. Experiment and find combinations that you and your family will love
