SAN FRANCISCO (CBS SF) — San Francisco’s JeffThe420Chef hosted a cooking class Saturday to share the recipe for his signature “light-tasting” oils and butters infused with pot.

The inventor of Cannabutter eschews cooking with chopped pot, preferring to incorporate his special oils and butters into recipes mixed with other conventional herbs, like rosemary. The recipes on his website include CannaBaby Love Bites (brownies), CannaCherry Glazed Ham, and Happy Apple Pie.

“While cannabis is legal for recreational use in Colorado, Washington, Oregon, Alaska and DC, as well as for medical use in 20 states, it is still technically illegal under federal law. Do this at your own risk. Remember: edibles require longer to take effect (anywhere from 30 minutes to 3 hours) and hit way harder than smoking, and the effects last longer (anywhere from 2 to 12 hours depending on the strength of the butter and the amount of edibles you ingest). Do not attempt to drive, operate heavy machinery, make business decisions, or do anything that requires a fair amount of serious thought.”
