The first time I got to gather this mushroom in quantity occurred when some mushroom lovers and I drove to a seashore habitat that had lots of pine trees. We were so happy to bag so many mushrooms, we left one person behind when we left (he was one of those slim, quiet, unobtrusive people who easily escape notice, and the car was quite crowded!)
After we returned and rescued him from complete oblivion, I went home and sautéed the mushrooms. They became a slimy, tasteless mess.
Next I peeled away the slime layer (which gives some people diarrhea) and made a cream soup with more of the mushrooms, pureeing them in blender with the other cooked soup ingredients. They were superb, and that's how I now recommend preparing them and other Suillus species.
