Slowly toast the seeds in a dry pan (without oil) on LOW heat if using a gas fire and medium-low for an induction stove.
Stir continuously (or shake the pan) for 5-12 minutes till you smell the toasted, warm aroma of sesame.
You may want to let your seeds cool slightly before blending with the sesame oil.
Add the sesame oil now as most blenders need some help to get going.
Blend in intervals of 5-10 seconds, allowing your motor to rest in between to prevent overheating.
Optional: you may want to blend in a pinch of salt to enhance the nutty flavor.
You know the black sesame paste is done when it changes from a grey gritty powder to a glossy and shiny jet black puree.
If making sweet black sesame paste: stir in the honey or syrup, to taste.
