Preheat oven to 400°F (20°C). Cut an X shape into the rounded side of each chestnut — this prevents popping. Place flat-side-down on baking sheet and roast 20-25 minutes, until fragrant.
1 cup chestnuts
Let chestnuts cool, then peel off the hard shell. Discard the shells.
To a medium saucepan, add peeled chestnuts and pecans. Sprinkle with 1 teaspoon brown sugar. Toast over low heat, 10-15 minutes, stirring frequently to prevent burning.
¼ cup chopped pecans, 1 cup brown sugar
Add the remaining brown sugar, spices and water. Cook at a low simmer for 10 minutes. Strain using a fine mesh strainer.
1 cup brown sugar, 1 pinch nutmeg, 1 pinch cinnamon, 1 cup water
Let cool completely. Store in a food-safe, airtight container such as a mason jar in the refrigerator for up to 1 month.

Pour the chestnut praline syrup into a mug, then top with hot espresso.
½ ounce chestnut praline syrup
Spoon slightly-cooled steamed milk over top. Dust with a pinch of nutmeg or other toppings, if desired.
