Step 1

To prepare your weed you will need to grind it up as much as possible. This will increase potential surface area and allow for a much better reaction when the time comes to meld it with butter. The best way we have found to do this is by using a food blender. You can turn whole bags of trimmings into a fine paste in a matter of minutes.

Step 2

Choose a cooking pot that you can fill to 1/3 capacity with your blended marijuana. If you are making a small batch, then choose a small pot; if you are making a big one, then choose a big pot/multiple pots in accordance.

Step 3

Add sticks of butter and water into your pots at a 1:4 ratio. So for every 250g stick of butter you add, add in one liter of water (1000 ml). Do this until you fill all the pots you are using to 2/3 capacity.

Step 4

Now that you have a weed and butter “soup” in your pots it is time to start heating them up. There are two opposing options here, with options being hotly debated. You can either bring your water to a very high temperature causing a fast and violent boil, or you can hit 100 degrees Celsius and boil it slowly. Violent boiling will be much faster, but you run the risk of losing THC and CBD particles in the accelerated evaporation/vaporization. Lower boils will take much longer, but you are likely to lose less THC and CBD

Step 5

As you boil the mixture, stir it regularly with your wooden spoon and keep topping it up with water when it reduces by half the original volume. Depending on the speed you boil it will dictate how frequently you have to do this.

Step 6

You know your butter is ready when you see a separation in the liquid, with a decent layer of oil floating on the top. This can take anywhere from 3 hours to a whole day.

Step 7

Once you have this, strain the liquid into a container, removing the blended marijuana. Take this marijuana, and with gloves on, hand squeeze it over the container and another sieve to get additional oil out of it. There will be quite a lot left in the weed you have taken out – you should be able to get some substantial amounts out of it.

Step 8

You are now left with a container that has a layer of cannabutter oils on top of a layer of water. Place the container in the fridge overnight. This will solidify the oils into your final cannabutter.

Step 9

When you come back the next day, carefully remove the layer of cannabutter from the container. Be careful not to spill any of the water by-product or drop the butter into it, it can make a nasty mess.

Step 10

Now that you have your marijuana butter, you can store it in the fridge. It should last about 2 weeks or so before it begins to go off. If you want it to last longer, you can store it in the freezer for use at you own leisure. Bear in mind you will have to let it thaw before use though, so it is best to cut it into portion sized chunks before you freeze it. This will mean that you do not have to thaw your entire stock when you want to use some.
