Preheat a grill for indirect cooking or a smoker to 275 degrees F (135 degrees C).Tip: As this is a dessert, it can easily be placed in a barbecue after you have taken the main course out to use the residual heat while eating.
Ricotta Stuffing
Combine the ricotta cheese, brown sugar, honey, walnuts, and lemon zest in a bowl.
Once well combined, put aside until needed.
Maple Whiskey Glaze
Combine the maple syrup and whiskey in a bowl.
Crumble Topping
Place the biscuits in a ziplock bag and crush until crumbed.
To Cook
Clean the pears then slice in half longways and remove the seeds with a spoon to create a dint.
Place the pears in the baking dish flat side down and brush with the Maple Whiskey Glaze. Turn the pears over and brush the other side with the glaze.
Place a large spoonful of the ricotta filling in each pear so as to use up all the filling across the eight pear halves.
Sprinkle the crushed biscuits over the pear filling, then drizzle with the additional maple syrup.
Place the pear-filled baking dish in the preheated barbecue and cook until soft. Depending on the size and firmness of the pear, this can take 30 to 60 minutes. Tip: the softness of the pears can be checked by inserting a skewer and feeling the resistance.
