With the rise of legal cannabis in the UK, more people are experimenting with homemade edibles. Whether you’re in London, Manchester, Birmingham, or Glasgow, cooking with cannabis gives you a discreet and delicious way to enjoy weed.
However, making potent and tasty cannabis edibles is more than just tossing weed into brownie batter. Newcomers often make costly mistakes that waste time, money, and THC. To help you perfect your cannabis-infused treats, here are 10 common mistakes to avoid when cooking edibles in the UK.
Cannabis must be decarboxylated before cooking. Raw weed contains THCA, not THC, meaning it won’t get you high until it’s activated by heat.
🔥 Preheat oven to 110–120°C (230–250°F).
🔥 Break up cannabis buds and spread them on a baking sheet.
🔥 Bake for 30–45 minutes, stirring occasionally.
Once decarbed, your cannabis is ready for making cannabutter, infused oils, or directly adding to recipes.
You don’t need expensive buds for edibles. While premium strains from dispensaries in Leeds, Liverpool, or Nottingham might be great for smoking, edibles work just as well with:
✅ Trim, shake, and small buds
✅ Kief and leftover stems
✅ Mid-range cannabis strains
Since heat extracts THC efficiently, there’s no need to waste premium-grade flower.
Many people assume they should grind cannabis into a powder—but that’s a mistake! Overgrinding can:
❌ Make edibles taste too “green”
❌ Cause a gritty texture in baked goods
❌ Increase plant matter absorption into oil (making it bitter)
Instead, lightly break apart buds or use a coarse grind before infusing them into butter or oil.
If you’re making cannabis butter or oil, always add a little water to prevent burning.
💧 Water helps regulate temperature and keeps butter from scorching.
🍃 It reduces the grassy, bitter taste by minimizing excess chlorophyll.
For best results, use a slow cooker on low heat for 4-6 hours, stirring occasionally.
Cannabis is sensitive to high temperatures. If you cook it at too high a heat, you’ll burn off the THC before it even gets into your edibles.
🔥 THC degrades above 200°C (392°F)
🔥 Keep baking temperatures below 180°C (350°F)
For frying or sautéing, use low heat and infused oils or butter to prevent cannabinoid loss.
One of the biggest mistakes new bakers make in London, Edinburgh, or Belfast is adding too much cannabis. Edibles take longer to kick in—leading some to overdose accidentally.
💡 Start with 5–10 mg of THC per serving.
💡 Wait at least 2 hours before taking more.
Remember: You can always eat more, but you can’t eat less!
On the other hand, some people underestimate their dosage, resulting in weak, ineffective edibles.
If your batch is too weak, don’t throw it away! Instead:
✔ Eat a slightly larger portion next time.
✔ Use leftovers in smoothies, coffee, or additional recipes.
✔ Take notes on dosage for better results in your next batch.
Even distribution of THC is crucial. If you don’t mix your cannabis butter or oil evenly, one brownie might barely work while another knocks you out.
📏 Know your THC percentage. (E.g., 20% THC = 200mg per gram)
🍪 Divide total THC by the number of servings.
📝 Use kitchen scales to measure portions accurately.
For example:
Many people use hash, kief, or concentrates in their recipes, but forget to decarb them first.
✅ Kief blends well into oil or butter—just decarb it first.
✅ Hash must be broken down and mixed thoroughly.
✅ Dabs, distillates, and live resin work great but should be carefully measured for potency.
Many people forget to balance the cannabis taste in edibles. To enhance flavor:
🌿 Use herbs and spices like cinnamon, vanilla, nutmeg, or cocoa.
🍋 Add citrus zest (lemon, orange) to balance bitterness.
🍫 Pair with chocolate or coffee for a rich, indulgent taste.
Seasoning makes a huge difference, especially in UK bakeries experimenting with infused pastries.
Cannabis edibles are growing in popularity in London, Manchester, and Bristol, and avoiding these mistakes will ensure you get the best results.
✔ Decarb your cannabis—otherwise, it won’t work.
✔ Measure THC dosage carefully to avoid surprises.
✔ Use the right cooking temperatures to preserve cannabinoids.
✔ Start with a small dose and adjust as needed.
✔ Have fun experimenting with flavors!
Whether you’re making brownies in Birmingham, gummies in Glasgow, or cannabutter in Cardiff, mastering the art of cooking with cannabis will take your homemade edibles to the next level. Enjoy responsibly! 🍪🌿
