Roast the nuts for 10 minutes in the preheated oven at 150°C (302°F)
Gently heat the glucose in a saucepan over medium heat, then sprinkle the sugar over it. Let it caramelize, stirring occasionally. The sugar tends to clump together, but by stirring and pressing it against the saucepan, it will gradually liquefy while coloring. The caramel should not be very dark in color.
Meanwhile, while the sugar caramelizes, heat the liquid cream in a saucepan.
Once the sugar has taken on a beautiful golden color, remove the saucepan from the heat and temper it with the warm cream. Pour the cream in 3 times, stirring constantly with a wooden spoon. Be careful of splatters.
Scrape the bottom of the saucepan well to melt all the caramel crystals. (Refer to the video above for a clear demonstration of the method.)
Pour into a bowl and add the pecans on top. Mix to coat them with caramel.
You can strain the caramel through a sieve if there are any sugar crystals remaining.
Pour into the pie crust and arrange the pecans on top in a harmonious manner. Drizzle with the remaining caramel at the bottom of the bowl.
Allow to set in the refrigerator for 1 hour before serving and enjoying.
