Press a sage leaf onto each sausage lengthway, then wrap sausage with thinly sliced piece of streaky bacon.
Mix maple syrup, whole-grain Dijon mustard, and pinch of nutmeg in small bowl and set aside.
For Air Fryer: Air fry on Roast setting at 180°C (356°F) for 6-10 minutes until bacon has slight color and is turning golden.
Pour maple syrup mixture over sausages and return to air fryer. Continue cooking until bacon becomes crisp and sauce forms glaze, approximately 2-4 minutes.
For Oven: Preheat oven to 190°C (374°F). Place wrapped sausages in oven and bake for 8-12 minutes until bacon has little color.
Pour maple syrup mixture over sausages and return to oven. Continue baking until bacon becomes crisp and sauce coats sausages in glaze, about 3-5 minutes.
Baste sausages while roasting for extra stickiness and serve immediately.
Notes
Cooking time depends on thickness of sausages. Cocktail sausages require half rasher of bacon and reduced cooking time.
Press sage leaves firmly onto sausages before wrapping. Any small, thin sausage works well – avoid hot dog style sausages.
Can be prepared ahead and stored in refrigerator for up to 48 hours before cooking.
