Turn the heat down to low and let it cook whisking constantly for another minute until smooth and thick
Take the pan off the heat and stir in the pumpkin, vanilla and spices. Add more maple syrup to taste
Divide the mixture between 4 serving dishes, cover with clingfilm and chill until cold
Meanwhile put the pecan nuts, butter and sugar in a small skillet and place on medium-low heat. Stir to coat and let them caramelize, then take the pan off the heat and spread the nuts on parchment paper to cool
