1 ounce of your favorite cannabis flower
1 pound (4 sticks) of unsalted butter
Cheesecloth or fine strainer
Saucepan
Baking tray and parchment paper
Grinder (optional)
Step-By-Step Guide
Step 1: Decarboxylation
Preheat your oven to 240°F (115°C), which is the optimal temperature for decarboxylation. Grind your cannabis until it’s coarsely ground (not too fine). Spread the ground cannabis evenly on a baking tray lined with parchment paper. Bake for 30-40 minutes, stirring every 10 minutes to ensure even heating. Your cannabis should turn a light to medium brown color and will be very dry.
Step 2: Slow Simmer
While your cannabis is cooling, melt your butter in a saucepan on low heat. Once the butter has melted, add your decarboxylated cannabis into the pan and stir well. Simmer the mixture on low heat (ideally between 160°F and 200°F) for 2 to 3 hours. Stir occasionally. This slow simmer allows for full extraction of the cannabinoids.
Step 3: Straining
After simmering, strain the mixture through a cheesecloth or a fine strainer into a glass container. Be sure to squeeze out as much liquid as possible from the plant material. Discard the leftover plant material.
Step 4: Cooling
Cover the glass container and refrigerate it for a couple of hours. The butter will rise to the top, separate from the water, and solidify.
