Cooking with cannabinoids has become increasingly popular as more people look for alternatives to smoking or vaping. Whether you’re interested in experimenting in the kitchen or learning about hemp-derived ingredients, there are now more options than ever before.

Why Cook with Cannabinoids?
Many people prefer incorporating cannabinoids into food because it offers an alternative method of consumption.
Potential advantages include:
- Smoke-free preparation.
- Precise recipes using measured ingredients.
- Versatility across sweet and savoury dishes.
- The ability to use purified cannabinoid isolates.
Understanding Decarboxylation
Decarboxylation is a heating process that changes naturally occurring cannabinoid acids into their active forms.
Without this step, many cannabinoids remain in their acidic form and behave differently during cooking.
Basic Decarboxylation Method
- Preheat the oven to approximately 110–120°C.
- Break plant material into small, even pieces.
- Spread evenly across baking parchment.
- Heat gently for around 30–40 minutes.
- Allow to cool before use.
Temperature control is important, as excessive heat may degrade cannabinoids and terpenes.
Making Infused Butter
Infused butter (often called cannabutter) forms the basis of many traditional edible recipes.
Ingredients
- 250g unsalted butter.
- 300ml water.
- Prepared plant material (where legally appropriate).
Method
- Melt the butter together with the water over a low heat.
- Add the prepared ingredient.
- Simmer gently for 2–3 hours without boiling.
- Stir occasionally.
- Strain through muslin or a fine sieve.
- Allow to cool and refrigerate.
- Separate the solid butter from the remaining water.
The finished butter can then be incorporated into a wide variety of recipes.
Using CBD and CBG Isolates Instead
Many people now prefer using purified cannabinoid isolates rather than preparing infused butter from plant material.
CBD and CBG isolates offer several practical advantages:
- Approximately 99% purified cannabinoid.
- Virtually flavourless.
- Easy to measure.
- Suitable for a wide range of recipes.
- No lengthy infusion process.
You can learn more about these products in our CBD & CBG Isolates & Extracts section.
Ideas for Using Isolates
Purified cannabinoid isolates can be incorporated into numerous recipes, including:
- Smoothies.
- Protein shakes.
- Brownies.
- Cookies.
- Chocolate.
- Sauces.
- Hot drinks.
- Salad dressings.
Because isolates contain very little flavour, they integrate easily into many recipes.
