Step 1Heat the oven to 350 degrees. Place the pecans in a single layer in a shallow pan and toast for about 8 minutes.
Step 2Transfer the warm pecans to a bowl and drizzle with the oil. Toss to make sure the pecans are completely coated with oil. Sprinkle in the salt and maple sugar and toss again. Drizzle the maple syrup into the bowl and toss well.
Step 3Arrange the pecans on a baking sheet and bake for 7 to 10 minutes. Allow to cool completely. Store in an airtight container.
Step 1Heat the oven to 300 degrees. Put the sugar and water in a heavy-bottomed pot and cook on medium-high heat to a golden brown caramel, about 15 minutes.
Step 2Pour the caramel into 10 (4-ounce) ramekins, swirling so that the caramel coats the bottom of each ramekin. Allow to cool so that the caramel sets.
Step 3Combine the maple syrup, eggs and vanilla extract in a blender. Pour the evaporated and condensed milk into a large bowl. Vigorously whisk in the maple syrup mixture until it is fully combined. Pour the mixture into the prepared ramekins.
Step 4Place the ramekins in a baking pan filled halfway up the sides with water. Cover the pan and ramekins with foil and bake until the custards are just set, about 1 hour to 1 hour 15 minutes.
Step 5Remove the pan from the oven and the ramekins from the water bath. Allow the custards to cool, then chill them, covered, in the refrigerator. The custards can be made up to several days ahead.
Step 6To serve, invert to unmold the custards, letting the caramel spill out over the top. Crush some maple pecans and scatter them, along with some whole pecans, over and around each creme caramel.
