- Heat the oil in a large stockpot over medium-high heat.
- Place 2–3 kernels in the oil and cover the pot. When these kernels pop, add the rest of the kernels in an even layer. Cover the pot and let pop, shaking gently to ensure all kernels pop.
- When popping slows to several seconds between kernels, remove the pan from heat.
- Add melted cannabutter and mix well.
