Before you can get busy making magic, you have to set the stage.
With edibles, it isn’t enough to just toss a handful of bud into the sauce and call it a day. There is a critical step necessary to make a lifted meal – decarboxylation.
DECARBOXYLATION
What is this and why you need to do it
Simply put, decarboxylation is making raw cannabis flowers psychoactive.
This is done by using a low heat to turn tetrahydrocannabinolic acid (THCA) into Delta 9-tetrahydrocannabinol (THC). This process occurs automatically when you combust the plant, ie. Spark-up a joint or a bong. Once the herb is decarboxylated, it becomes psychoactive and can be used to infuse fats and alcohol, or even eaten as-is if that’s your preference.
Cannabis flowers are the buds of female plants. They are covered with trichomes which contain terpenes. The ones that get the most attention are THC and CBD (cannabidiol).
You can’t just use raw flower in cooking. The psychoactive chemical that gets you lifted is in the form of THCA. You need to get rid of the A and that’s done with heat.
Going forward, on this blog decarboxylation means to bake your weed at 240 F (325 C) for 30-40 minutes.
This is a basic procedure but is not the only way. Many variables can be manipulated, including time and temperature, all with the goal of customizing the experience, ie. which terpenes are being activated. You can make this as simple or as fussy as you like. Regardless, to put it in food you need to heat the flower first. You are encouraged to explore other techniques and procedures to discover what works best for you.
Basic Procedure for Decarboxylating Cannabis Flower
Decarboxylation is the name for changing THCA into THC by heating the cannabis 240 F for 20-40 minutes.
There are two main ways to decarboxylate:
- Conventional oven – almost everyone has access to an oven. Make certain to cover your herbs with tinfoil or use an oven-proof and smell-proof container as things can become rather fragrant.
- Coarsely grind your buds.
- Place in an oven safe dish or on a parchment lined cookie sheet and cover with foil to minimize the smell
- Toast your flower 240 F (115 C) for 20-40 minutes. Rule of thumb, the shorter the time, the higher the temperature. Adjusting the time and temperature will allow you to activate different terpenes to achieve different effects.
- Let cool. Store in an airtight container in a cool, dark place.
- Sous vide – Sous vide is a type of low temperature, long time cooking. The main advantage is more THCA is converted to THC, and the smell is considerably reduced. The downside is it takes longer and you have to buy specialized gear (the immersion blender or water water bath)
- Seal ground bud in a freezer safe resealable plastic bag, vacuum-sealed bag, or a mason jar. If using a freezer bag, place your ground cannabis in the bag. Add something to weigh it down or it will float to the surface. Immerse the bag in the water, which will push the air out. Seal the bag.
- Set your sous vide device (an immersion circulator or water bath) for 90 minutes at 203 F (95 C)
- Immerse cannabis
- When time is up, remove from water and let cool. Store in a glass jar with a lid in a cool, dark place.
