Hashish has a long history. Today, both modern and traditional methods are used to make
concentrates. This dry sift and hot press hash making method leans to the traditional and is
based on Ed Rosenthal’s book, Ask Ed: Marijuana Gold – Trash to Stash.

We dry our trim, bag and freeze it until we have enough to make a batch of hashish.

No chemicals, ice or dry ice are used. Steaming heats the trichomes without burning them. Hot Rolling continues to melt the trichomes which break and release their oil. Pressing completes the process by applying heat and pressure to make the pieces dense and consistent.

Different types of Cannabis produce different colours of hashish; this is why we have Red Lebanese, Blonde Lebanese and Black Afghan. Less heat will produce a lighter color and consistency. More heat will release more oil and create a darker product with a shiny surface. Going too hot, however, will cause oil to leak out and the hash will become over saturated.

Ed’s Hash Making Recipe

The recipe is simple. Steam for thirty minutes. Roll for twenty minutes. Press for an hour.
The hash will be fully decarboxylated when done, unlike water hash. The hash after curing for a couple of days can now be used for cooking or consumed with no further preparation.

Recipe:
1. Collect the resin
2. Make the packets
3. Steam, roll and press
4. Strip the packets

1. Collect the Resin

Freeze your absolutely dry material before starting. Use high quality trim or bud. Store trim in the freezer to keep it fresh. The glass blender jar also goes in the freezer. My trim tray is too large to fit so it goes outside in a garbage bag to chill if the weather is cold enough. Keep everything as cold as practical while processing.

The frozen cannabis is blended to a fine consistency before screening to speed up the process. A higher grade of sift can be achieved by lightly screening without blending but it is a lot more work and yields less.

Use a flexible plastic or silicon card to move the material over the screen while applying
moderate pressure. The first drop through the screen yields the highest quality resin. Stop when the screened material starts to turn from gold to green. Screen less heavily for better quality and more heavily for greater returns.

Discard the leftover or make oil (see oil making). The small amount of resin left is not worth trying to extract. My returns typically run 20-25% by weight. Therefore you will need about a quarter pound of high quality trim or bud to produce an ounce of hash.

I used to screen and press each strain separately but now they all go in together. Results are more consistent and it’s easier to make similar size packets. Testers approve.
Collect the resin in a glass jar until ready to use.

Tip: Trim sugar leaves into one box and fan leaves and leaf tips into another to high grade your trim with no further sorting.

For screening, I use a large Mogobe stainless steel trim tray which is 19&1/2” by 13&1/2” by 3” deep with a 150 micron stainless steel screen. Trichomes come in a variety of sizes and the 150 screen lets both the large and small through.

Clean the screen with rubbing alcohol or methyl hydrate if necessary. Keep your material cold enough and you will never need to clean the screen.

You can start with a smaller screen box but it can be hard to find one with the right size screen. The Mogobe tray is way faster and yields a similar result.

2. Make the Packets

Packets must be made from cellophane and never plastic. Cellophane is made from plant
material and does not stretch. It is often used to wrap flowers. Gift cards sometimes come in cellophane envelopes and these envelopes are also available at the craft store and on Amazon.

Heavier is better. The packets must be water tight for steaming and heavy duty to withstand the pressing. Making up envelopes from heavy cellophane is time consuming but straightforward.

An easier method is to use a good quality cellophane envelope and tape all the edges.
Use good quality painter’s tape to seal the packets. Fill the packets, then double fold and seal the opening. Pierce a small hole if necessary to let the air out. Reinforce the edges of any premade envelopes with tape.

Smaller packets can accommodate a quarter ounce and larger packets can hold a couple of
ounces. Multiple envelopes should be the same size or at least a similar thickness for pressing. Wrap the packets with several layers of newspaper or brown packing paper. Seal with painter’s tape. Soak the packets in water. They are now ready for the frying pan!

3. Steam, roll and press

Place the packets in a heavy stainless or cast iron frying pan with a lid. Add enough water to
cover the bottom of the pan. Heat and gently steam the packets. Flip and press the packets
regularly. Keep adding water as required until time is almost up, then let the packets start to dry out.

You may need to make a pin hole to let the air out if the packets start to swell up. Water will
stain and lower the quality of the hash so keep any pin holes small.
Steam for thirty minutes, roll for twenty minutes and press for one hour.

Set the oven to the desired temperature and preheat the stone pieces while steaming the
packets. The oven temperature can be set from 230F up to 300F. Start at the lower end of this range for your first batches. Try 240 degrees Fahrenheit. Keep the stone implements in the hot oven until ready to use to get consistent results.

Roll the packets for twenty minutes after they come out of the frying pan. A marble rolling board and pin are best although a bottle filled with boiling hot water can be used. Keep rolling and flipping the packets so they become melted and pliable.

Time to press! Take the stone plates from the oven and set them up with plywood backers. Set the press up on a couple of 2×4” pieces to allow clearance for the clamps. Insert the hash packets between the stone plates. Clamp. A six inch C clamp works well; tighten as much as possible. Tighten in rotation to keep the pressure even. Use a minimum of four clamps.

You can find stone cut offs and tiles at any granite or stone shop. Cut off pieces can often be had for the asking. Granite works well but can break under pressure. One foot square granite floor tiles with fiber backing work well. Marble tiles also work well. You will need two pieces as well as two pieces of plywood of the same size for backers.

Let the press stand for an hour as it starts to cool. Place the warm packets in the freezer for
twenty minutes to cool and harden. This allows the cellphone to be more easily stripped.

4. Strip the packets

The best moment comes when the cellophane is stripped off and the finished pieces are
exposed for the first time. If the cellophane is sticking, rub it with an ice cube and ease it off.

The hash needs to sit exposed to the air for a few days to cure. It can then be bagged and
stored. Any extra is best stored in the freezer. Good quality hash will fluff up when gently heated with a flame.

It can then be easily mixed with cannabis to roll a super charged joint. Small chunks can be cut off and smoked on a pin. Light one end and inhale through a paper straw. Of course, there is always the pipe, bong or rig if that’s your choice. Enjoy!

Enjoy!
