Combine canola oil and garlic in a small saucepan and cook over medium-low heat, stirring, until it starts to brown. Reduce heat to low and continue to cook, stirring frequently, until garlic turns completely black, about 10 minutes . Transfer mixture to a heat-proof bowl and add sesame oil. Transfer to a blender and blend on high speed until completely pulverized, about 30 seconds. Transfer to a sealable container and store in the refrigerator for up to 2 months.
