To a large pot over medium heat, add the apples + water. Cover with a lid + stew for 15 minutes.
Remove the lid, add saffron + a little more water, then allow to simmer until all the water has evaporated.
Remove from the heat, then add in the chocolate + tahini. Blend until completely smooth + glossy.
Pour the mixture into a lined 8-inch cake tin + place in the fridge overnight to set.
Using a hot knife (dip the blade into hot water, then dry completely), slice + enjoy.
