Cooking With Cannabis At Home

Decarboxylation (decarb) is the activation step in cannabis cooking. Raw cannabis contains THCa (tetrahydrocannabinolic acid), the non-intoxicating precursor to THC. Heat converts THCa to active THC.

The simplest decarb method is the oven. Spread ground cannabis (lightly broken up but not powdered) on a parchment-lined baking sheet. Bake at 240 degrees Fahrenheit for 30 to 40 minutes. The cannabis should turn lightly golden brown and develop a stronger aroma.

After decarb, the cannabis is ready for infusion into fat (butter or oil) or alcohol.

Decarbed cannabis can be stored in an airtight container in a cool, dark place for up to several months.

The two most common home infusions are cannabutter (cannabis-infused butter) and cannabis oil (typically coconut oil, olive oil, or other neutral cooking oil).

Cannabutter. Combine 1 cup of butter with 1 cup of water and 7 to 14 g of decarbed cannabis. Simmer at low heat (around 160 to 180 degrees Fahrenheit) for 2 to 3 hours. Strain through cheesecloth into a container. Refrigerate. The cannabis-infused butter solidifies on top; the water separates below and can be discarded.

Cannabis coconut oil. Same method substituting coconut oil for butter. Coconut oil has high saturated fat content, which efficiently absorbs cannabinoids.

Cannabis olive oil. Same method with olive oil. Olive oil is suitable for low-heat applications like salad dressings and drizzles. Lower cannabinoid absorption efficiency than butter or coconut oil.

The fat-soluble cannabinoids dissolve into the fat during the slow simmer. Strained infused fat can be used as a direct substitute for regular butter or oil in baked recipes.

The most important step in cooking with cannabis is calculating the total THC and dividing it across the batch.

Example: A consumer uses 7 g of cannabis with a 20 percent THC concentration (from the COA).

Total THCa in starting cannabis: 7 g times 200 mg per g times 0.875 (decarb conversion efficiency) = approximately 1,225 mg of THC.

Realistic infusion efficiency: 50 to 70 percent of the available THC transfers into the fat. Assuming 60 percent infusion efficiency: approximately 735 mg of THC in the infused batch.

If 1 cup of cannabutter is used in a recipe that yields 16 cookies: each cookie contains approximately 46 mg THC.

This dose level exceeds the 10 mg per serving cap for commercial NYS edibles. Home-infused doses are not regulated, but consumers should treat home-infused doses with the same caution.

Recommended starting dose for home-infused: 5 to 10 mg THC per piece for new consumers; 10 to 20 mg per piece for experienced consumers. Adjust the cannabis input quantity accordingly.

To produce lower-dose home edibles, reduce the cannabis input or dilute the infused fat with regular fat.

Example: To produce a 5 mg per cookie batch from the same recipe yielding 16 cookies, the total THC in the batch should be 80 mg. Working backward, this requires roughly 0.75 g of starting cannabis (assuming the same potency and efficiency).

Smaller cannabis quantities can be challenging to infuse efficiently. An alternative is to make a higher-potency infused fat and dilute it with regular fat in the final recipe.

Cannabis-infused recipes generally fall into several categories.

Baked goods. Cookies, brownies, cakes. The infused fat substitutes for regular fat in the recipe. Cook temperature should stay below 350 degrees Fahrenheit to avoid THC degradation.

Stovetop dishes. Pasta sauces, sautés. Add infused fat at the end of cooking rather than at the start, to minimize THC degradation from prolonged heat.

Cold dishes. Salads, dressings, drizzles. Infused olive oil is excellent for cold dishes. No heat means no further THC degradation.

Beverages. Cannabis-infused beverages can be made with cannabis tinctures rather than infused fats. Tinctures incorporate easily into both hot and cold drinks.

Dairy infusions. Cannabis-infused milk or cream for hot chocolate, coffee, or cereal. Same simmer method as cannabutter but with dairy.

Test a small dose first. Eat a small piece (1/4 to 1/2 of an intended serving) and wait 2 hours to gauge potency.

Label everything. Use clear "Cannabis Infused" labels on storage containers. Date the labels.

Store securely. Cannabis-infused food should be stored in a locked or out-of-reach location away from children, pets, and adults who have not consented to consume.

Refrigerate or freeze. Cannabis-infused fats are stable in the refrigerator for several weeks and in the freezer for several months.

Don't combine with alcohol the first time. Test the home dose alone before pairing with alcohol.

Have non-infused alternatives. When cooking for a mixed group, prepare both infused and non-infused versions clearly labeled.

Overheating the cannabis. Temperatures above 350 degrees Fahrenheit degrade THC. Keep oven temperatures lower for baked goods.

Skipping decarb. Without decarb, the infused fat contains primarily inactive THCa. The edible will not produce the expected effect.

Skipping the dose math. Estimating the dose without calculation produces inconsistent edibles and risks overconsumption.

Eating too much too fast. Home infusions can vary in potency. Always test a small portion first and wait 2 hours before increasing.

Mixing cannabis food with regular food. Clear labeling and physical separation prevent accidental consumption.

The customer who walked into the Flatiron store on a Saturday in January and said "I want to make brownies for a dinner party of six adult friends, none of them experienced, what do I need" walked out with a 7 g jar of mid-tier indoor flower at 20 percent THC, a notebook page of dose math, and a clear recipe outline. The conversation took 18 minutes and is worth reproducing because the dose math is the part most home infusers get wrong.

The target dose was 5 mg per brownie. The recipe yielded 16 brownies. Total THC needed for the batch: 80 mg.

Working backward through the efficiency chain: at 60 percent infusion efficiency and 87.5 percent decarb conversion, the starting cannabis needed to deliver 80 mg of available infused THC requires approximately 152 mg of THCa in the starting flower. At 20 percent THC concentration (200 mg THCa per gram), that is approximately 0.76 grams of starting flower.

The customer used 1 gram of flower as a round-number safety margin, accepted that the resulting brownies would be approximately 6.5 mg per piece, and reported back two weeks later that the dinner went smoothly with one friend requesting half a brownie because of low tolerance. The other five took full brownies and the evening proceeded as planned. This is the right kind of home infusion: low dose, dose-counted, dose-known.

The opposite story is the customer who used a full 7 gram jar in a single batch of brownies, did not do the dose math, and ended up with brownies estimated at over 70 mg THC per piece. That batch was inedible at the intended serving size and the customer was stuck either re-cutting each brownie into eighths or composting the batch. Dose math is not optional.

Cannabis cooking involves multiple temperature exposures, each of which degrades a small percentage of the active cannabinoids. Understanding where the loss happens helps preserve potency in the final product.

The decarb step itself loses approximately 12 to 15 percent of available THCa to overcooking or volatilization. The infusion simmer at 160 to 180 degrees Fahrenheit loses approximately 5 to 10 percent over a 2 to 3 hour window. The baking step at 325 to 350 degrees Fahrenheit loses approximately 10 to 15 percent of the THC in the fat over a typical 20 to 30 minute bake. Cumulative losses from raw flower to baked edible run roughly 30 to 50 percent of the theoretical THC content. Hence the 50 to 70 percent infusion efficiency assumption used in the dose math above.

Strategies to minimize loss include keeping the decarb at 240 degrees rather than 280 or higher, keeping the simmer covered to retain volatile terpenes and reduce evaporation, baking at the lower end of recipe temperature ranges, and adding infused fat as late in the cooking sequence as possible (drizzles, finishing oils, and post-cook butter pats lose almost no additional cannabinoid).

The aroma of a well-made cannabis edible carries the terpene character of the source flower. The aroma of a poorly-made cannabis edible smells generically like burnt herb. The difference is mostly terpene preservation.

Terpenes are volatile compounds with boiling points generally between 156 and 220 degrees Celsius (313 to 428 degrees Fahrenheit). At decarb temperature, terpenes evaporate. At simmer temperature, terpenes evaporate more slowly. At baking temperature, terpenes evaporate rapidly.

For consumers who want to preserve the cultivar character in a finished edible, the move is to add a small portion of fresh, un-decarbed cannabis to the infusion late in the simmer (last 15 minutes only, with a tight lid). The decarb is already done by the bulk cannabis added earlier; the late-add cannabis contributes mostly terpenes without significant cannabinoid activation. The resulting cannabutter carries a more characterful aroma and the finished edible tastes more like the cultivar rather than tasting generically "weedy."

This is an advanced technique. First-time home infusers should focus on the basic decarb-infuse-bake workflow before experimenting with terpene preservation.

Cannabutter stored in a sealed container in the refrigerator remains stable for 2 to 4 weeks. The fat itself can go rancid before the cannabinoids degrade meaningfully; smell-test before each use. Cannabutter frozen in small portions (silicone ice cube trays work well for measured portions) remains stable for 4 to 6 months.

Cannabis-infused coconut oil holds up slightly better than butter because of the higher saturated fat content. Refrigerator life of 4 to 6 weeks is typical. Freezer life of 6 to 9 months is typical.

Cannabis-infused olive oil is the most stable of the common infusions for short-term use, but the lower fat saturation means cannabinoid loading is somewhat lower. Refrigerator life of 2 to 4 weeks is typical.

Baked edibles store like their non-infused counterparts. Brownies and cookies remain stable for 4 to 7 days at room temperature in a sealed container, 1 to 2 weeks in the refrigerator, or several months in the freezer. Label every container with the date and the per-piece dose. The labeling is non-negotiable for household safety.

A cannabis-infused dinner with adult friends 21 and over is one of the legal home use cases for home-infused cannabis. The legal piece is the easy part; the etiquette piece is where most hosts get tripped up.

Every guest must consent to consume cannabis-infused food. Before the meal, walk through which dishes contain cannabis, what the per-serving dose is, what the onset window is, and what to do if anyone over-doses or feels uncomfortable. Have non-infused alternatives for any guest who declines. Have water, snacks, and a quiet space available. Avoid combining cannabis-infused food with significant alcohol. Have a plan for getting guests home (Uber, Lyft, sleepover offer); driving impaired by cannabis is a DWI offense in NYS.

The hosts at the most successful cannabis dinner parties we hear about at the counter all share the same approach: low dose per serving (5 to 7 mg is the sweet spot for mixed-tolerance groups), one infused course rather than every dish, clear labeling on the table, and a few sober adults who can keep the evening on track. Maximalist approaches (every dish infused, high doses, alcohol pairing, no exit plan) tend to produce stories that start with "well, the dinner was supposed to be fun" and end with "and then we called the paramedics."

For a NYC home infuser, the flower input matters. Buying from a NYS-licensed dispensary like The Alchemy provides COA-verified cannabis with known THC content, which is the prerequisite for accurate dose math. Buying from an unlicensed gray-market shop on a Manhattan corner provides no verified content, no testing assurance, and exposes the home infuser to flower that may have undergone pesticide treatment, mold contamination, or solvent residue from gray-market processing. The dose math is impossible without verified percentages.

The Alchemy flower selection that suits home cooking spans from mid-tier sun-grown lots at value pricing (good for high-volume cooking batches) through premium indoor at top-tier pricing (good for terpene-forward small-batch experimentation). Ask the budtender for COA-verified flower at your preferred price tier, and confirm the THC percentage at purchase so you have the input number for the dose math.
