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 estimating the total THC and dividing it across the batch. The figures below are approximations, since real yields vary by flower, method, and equipment, but the arithmetic gives you a usable estimate to work from.

Start with the flower's tested THC percentage, which appears on its certificate of analysis. Multiply the flower weight in grams by the milligrams of THC per gram that percentage represents. Then apply two reductions: a decarb conversion factor (a portion of the acid form converts to active THC) and an infusion-efficiency factor (only part of the available THC actually transfers into the fat, commonly estimated at somewhere in the range of half to two-thirds). What is left is a rough estimate of the total active THC in the batch. Divide that by the number of servings the recipe yields to get an approximate per-piece dose.

Home-infused edibles are not held to the per-serving cap that applies to commercial New York products, so a batch can easily land far stronger than a store-bought edible if you do not run the numbers. Treat home doses with at least as much caution.

A common approach is to aim low per piece and adjust the flower input up or down on the next batch. Test a small portion first and give it time before deciding it is weak.

To make lower-dose edibles, use less cannabis to begin with, or infuse a smaller amount of fat and cut it with plain butter or oil in the final recipe. Very small amounts of flower can be tricky to infuse evenly, so making a stronger infused fat and then diluting it is often more reliable than trying to infuse a tiny quantity directly.

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 dose math is the step most home cooks skip, and it is the one that causes the most trouble. A worked example makes it clear.

Say you are making brownies for a dinner party and you want each one to be a low, mixed-tolerance dose. Decide the per-piece target first, multiply by how many pieces the recipe yields, and that is the total THC the batch needs. Then work backward through the numbers below to figure out how much flower to start with.

Two failure modes are common. One is starting with a rough guess instead of a calculation, which produces an uneven and often far-too-strong batch. The other is dumping in the whole jar without dividing the total across the servings, which can leave each piece with an unmanageable amount. Both end the same way: a batch that is unpleasant or unusable at a normal serving size. Doing the arithmetic up front avoids it.

Cannabis cooking involves several rounds of heat, and each one degrades some of the active cannabinoid. That is why the dose math uses an infusion-efficiency figure well below 100 percent rather than assuming all the THC makes it into the food.

Loss happens at each heated step: during decarb, during the simmer, and during the bake. Higher temperatures and longer times mean more loss. You do not need exact percentages to cook well; you just need to know that the total that reaches the finished edible is meaningfully less than the theoretical amount in the starting flower, which is what the efficiency assumption accounts for.

A few practical ways to hold onto potency: keep the decarb at the lower recommended temperature rather than cranking the oven, keep the simmer covered to slow evaporation, bake at the lower end of a recipe's temperature range, and add infused fat as late in the cooking as you can, since drizzles and finishing oils lose almost nothing.

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.

Infused fats keep about as long as their plain counterparts. Cannabutter in a sealed container lasts a few weeks in the refrigerator and several months in the freezer; freezing it in small measured portions makes later dosing easier. The butter can turn rancid before the cannabinoids fade, so smell it before each use. Infused coconut oil tends to hold up a little longer than butter because of its higher saturated fat, and olive oil is fine for short-term refrigerator use.

Baked edibles store like ordinary baked goods: a few days at room temperature, longer refrigerated, and months in the freezer. Label every container with the date and the per-piece dose. The labeling is not optional, it is how you keep the household safe.

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.

A cautious approach tends to work best: a low dose per serving for a mixed-tolerance group, one infused course rather than every dish, clear labeling on the table, and a few people staying sober enough to keep the evening on track. Infusing every dish, dosing high, and pairing with a lot of alcohol is how a relaxed dinner turns into a rough night.

For home cooking, the flower you start with matters, because the dose math only works if you know the THC content. Cannabis from a New York licensed dispensary is lab-tested and comes with a certificate of analysis, so you have a real number to build on. Product from an unlicensed shop has no verified content and no testing behind it, which means you cannot dose accurately and you have no assurance about what is in it.

The Alchemy is a licensed New York adult-use dispensary that carries flower among its categories. The live menu shows what is in stock at each store, and staff can point you to options that suit cooking. Confirm the tested THC percentage when you buy so you have the input number for your dose math.
