Before making the caramel, make sure your work area is prepared. Have a silicone mat on a baking sheet on the counter ready for you to pour the molten caramel on top.
Place the sugar in a small saucepan over medium heat. Once the edges of the sugar start to melt, use a spatula to gently pull in the edges of the sugar so that it melts and caramelizes evenly. Continue to cook and stir until you have a rich golden shade.
Immediately remove from the heat and stir in the almonds so they are coated with the caramel. Pour the nuts and caramel mixture onto the silicone baking mat. Let it cool completely.
Transfer the hardened almond praline chunks to a food processor. Blend until you have a paste. This will take 5- 10 minutes. Scrape the bowl down as needed. You can go for a slightly chunkier consistency if you want. Set aside.
Place the white chocolate in a heat proof bowl and microwave for 30 seconds on 50% power. Set aside.
Place the cream in a small bowl and microwave in 10 seconds intervals until hot. Pour over the warm chocolate and stir until smooth. A few small lumps are fine. If the mixture is too cool or chunky, microwave in 5- 10 second intervals, stirring after each, until the ganache is smooth and warm.
Add the praline paste to the ganache and use an immersion blender to combine. Then add the butter, corn syrup and almond extract. Use the immersion blender to combine. The mixture should be smooth, thick, and glossy.
Press cling wrap onto the surface of the ganache. Let it sit at room temperature until it has cooled and has a peanut butter consistency. If you will not be using the ganache the same day, after an hour on the counter, you can cover the bowl and place in the fridge. Let the ganache sit on the counter for several hours to soften before using.
