Take 7 grams of cannabis buds and spread them evenly on an oven tray with baking sheet. Cover with silver foil.( do not grind the cannabis fine. Medium chunks does well)
Let the cannabis decarboxylate for 40 minutes.
While the cannabis is decarbing in the oven, take a lare cooking pan and get your bacon strips ready.
On low to medium heat, cook the bacon evenly for around 10 minutes untill all fat comes out of the bacon. Strain the fat through a sieve into a mason jar. ( do this in batches untill all bacon is cooked)
You should now have about 1 cup of bacon fat in the mason jar. Once cannabis is decarbed, place the buds in the mason jar which contains the bacon fat together witb the lecithin powder.
In a medium pot, fill with cold water and place your mason jar in it. Turn on the heat and let the cold water come to a simmer.
Let it simmer for 2 - 3 hours. Continue to fill water in the pan if some of it evaporates.
After 2 - 3 hours, strain your cannabis buds out of the bacon fat. Discard the cannabis. (All THC is now in the bacon grease)
Your bacon fat is now infused with THC.
Notes
Make sure that the mason jars you use are strong. Also, always make sure to start them off in cold water to avoid the jars shattering during the heating process.
