I take fresh pressed rosin put in a food grade container. I use a food grade silicone dab container set cover on top gently and put inside ceramic dish and cover with smaller ceramic dish in oven at 240 degrees, stir every 15 minutes until you see no bubbles. Usually takes about 40 minutes. Take rosin and pour into coconut oil and mix well about 10 minutes, then follow directions on box. I substitute coconut oil for butter and coconut milk for milk and I do the 24 muffin count. The muffins come out perfect. they’re probably about 25 to 30% mg THC each Krusteaz Gluten Free Wild Blueberry muffin mix.
