Generously brush a bowl with sesame oil.
Brush an 11”X17” parchment paper with sesame oil as well.
In a skillet or pan, over medium heat, add sesame seeds and toast until golden brown will take about 4-6 minutes. Stir with a spatula so the seeds will not burn.
Pour the sesame seeds immediately in the oiled bowl and set aside to cool down.
In saucepan over medium heat mix in sugar, honey, water, lime juice and vanilla if using.
Bring the mixture to a boil then reduce heat and simmer for about 5minutes.
Pour the honey mixture over the sesame and mix well to combine.
Pour the mixture over the parchment paper. Wet your hands with water and shape the sesame mixture into a square with the thickness you prefer.
Let it cool completely then cut into bars with a sharp knife.
Store in an air tight container at room temperature and separated by well oiled parchment paper.
