Place the chocolate, coconut oil, tahini, maple syrup, seas salt and orange zest in a large heatproof bowl. Set the bowl over a pan of simmering water (ensuring that the water doesn’t touch the bottom of the bowl) and melt gently, stirring occasionally.
Once the chocolate mix has cooled, stir through the mixed nuts, dried figs and most of the sesame seeds. Tip into a lined tin/mould (mine was roughly 20x12cm) and level out with the back of a spoon. Sprinkle over the remaining sesame seeds, then leave in the fridge to set for at least 2 hours
Once set, slice up and serve (keep refrigerated).
