This post might also fit over in the "unofficial cookbook thread" too.
There is a family of vines named Smilax, there are quite a few varieties of these in the wild. They are commonly green brier, cat claw, bull brier, etc..
In the spring they put on growth in the form of tender shoots that are edible. I had been reading about the old time uses of the roots and noticed the articles about eating the tips. The tips of the smilax vines are easily harvested, simply move along the new growth till it will snap clean between the fingers. That is where it become tinder enough to eat. Some folks eat it raw and other cook it. I choose to gather enough to cook. In the end I found the cooked green brier tips "melts down" similar to a pot of fresh greens, they simply shrink. The cooked tips were tasty and would certainly make fine table fare if you could gather enough without too much effort. MY wife said they tasted good because I cooked them in butter and salt.
Here is what the Smilax vine look like and the process I went through:

- Smilax (green brier) growing wild

- the mature part, the part that will get you

- A freshly harvested tip

- A mess of green brier tips in the black iron skillet, sauteing in butter seasoned with salt

- The shrank just like mustard greens

- Finished product, everyone said they were tasty!
I will try this again and gather enough to make a big skillet full. If you like the taste of asparagus, this will suit your palate.
