I'm no expert, but I would think it would be the same as smoking bud. If you don't dry it out first, you'll get that "green/grassy" taste. Probably has something to do with the chlorophyl in the plant material. Not to mention all the water you'd just have to cook out with the fresh material anyways. I would dry it first. Of course, since you're not worried about harshness of smoke, you could quickly dry it in the oven or something.
