Step 1

Set the immersion circulator to 200°F and place in a medium saucepan filled halfway with water. Grind the cannabis buds into small pieces and place in the vacuum-sealable bag with the distilled water. Using the vacuum sealer, seal the bag completely. When the circulator reaches 200°F, drop the sealed bag into the water and decarb for 30 minutes, rotating the bag every 5 to 10 minutes.

Step 2

Transfer the bag to a bowl of ice water to stop the cooking and to preserve the terpenes; let cool. Set a fine-mesh sieve over a bowl; strain and reserve the cannabis, discarding the liquid.

Step 3

In a small saucepan, combine oil and cannabis in a small saucepan and bring to a gentle simmer over medium heat; continue to cook for 20 minutes, stirring often. Remove saucepan from the heat and let steep for 30 minutes more.

Step 4

Strain the mixture through a fine-mesh sieve into a resealable heat-proof food container with an airtight lid. Keep refrigerated and use within 30 days.
