I made both yesterday. I used both collard and mustard greens, and added a touch of sugar to get rid of that bitter taste. Use plenty of bacon or salt meat and this sh!t is the bomb.
And, it's called "escarole" in the civilized world you friggin rednecks. It can be made with a little garlic and oil or even in a soup with mini-meatballs. I'll take you to my fav place in the city if you ever come this way.
Watched a Sanford & Son episode where Fred ate 8 day old collard greens and thought he was gonna die. It was bad gas...( He had to eat them beause it was stinking the house up to high heaven, and Lamont told him to get rid of them).LOL
