In a saucepan, heat sugar, water, and honey until it reaches 140°C (285°F). Use a candy thermometer.
While the syrup cooks, beat the egg whites with salt until stiff peaks form. Add vanilla powder here if using.
Soak gelatin sheets in cold water until soft. Squeeze out excess water. Stir into hot syrup before combining with egg whites.
Slowly pour hot syrup into egg whites while beating on high. Beat 5 minutes until glossy and thick.
Grease a silicone mat or parchment paper with vegetable oil. Pour the nougat and gently spread it with greased hands. Let rest uncovered overnight at room temp.
Make the Filling
Toast the hazelnuts in the oven for 10 minutes.
Toast the almonds. Set aside.
Blend hazelnuts until smooth. Add powdered sugar and blend again. Add sweetened condensed milk gradually until a soft, firm paste forms.
Roughly chop some of the almonds and mix it with the filling. Keep the remaining almonds for the nest day to coat the log.
Shape the filling into two logs and wrap them in plastic wrap. Refrigerate overnight
Work the Nougat
The next day, Grease the rolling pin with vegetable oil and roll out the nougat, fold and roll. Do this about 3 times.
Clean the silicon mat or use a new parchment paper and dust surface and rolling pin with cornstarch. Roll and fold nougat 3-4 times. Use extra cornstarch to manage stickiness.
Roll out nougat into a square. Place hazelnut log at the edges and roll inward.
Roll the nougat so that it forms two complete turns. Then, trim off any excess nougat.
Add Coating
Lightly wet your hands and the roll so it becomes tacky. Roll in chopped toasted almonds until coated.
Slice and Serve: Cut into 2 cm (3/4 inch) thick slices.
