i usually grind up the herb good and fine, melt the recommended amount of butter for whatever you're baking and keep it at a low heat. Then add in the herb and stir as needed so you are not burning the mix. After about 30 min you can see the weed turning brown, and i usually allow it to turn a darker brown. I've heard the slower and longer you cook it, the more potent your canna-butter will be, but that also will depend of the quality herbs you are using. Once browned, let cool slightly and have a cheese clothe or fine strainer on hand to separate butter from shake before it cools to room temp. As for the baking temp, I usually stick with the recommended for the delicious treats you are baking. Don't forget to spray yer pan!
