Tahini and chocolate fudge - "Halawa/halva" dessert

This one is nutty and extra rich. If you like tahini, you will enjoy. It's a slight twist on the middle eastern 'halawa/halva' recipe, which typically includes a mix of tahini (sesame seed paste) and sugar with nuts. I've used a small portion of maple syrup instead of sugar (to thicken the mixture) and dark, dairy free chocolate (cacao butter and cacao).
