Bring a small saucepan to a medium heat and melt the butter, honey, and salt together.
Remove from the heat and brush the mixture over one sheet of phyllo dough, top with another sheet and repeat. Refrain from brushing any butter on the last layer of pastry. Fold the phyllo so that it is the same width as the pan, then trim the corners and edges to fit over the apples. You want the layered phyllo to be slightly larger so you can tuck it in around the apples a bit.
Bake at 190℃/375℉ for about 20 minutes or until the phyllo crust is golden brown.
Invert the Tarte Tatin onto a serving dish. If any of the caramel is left in the pan, drizzle it on top and serving with the rooibos ice cream and roasted nuts.
