Step 1: Prep the Nuts
Preheat your oven to 350°F (175°C). Spread the nuts evenly on a baking sheet.
Roast for 8–12 minutes until fragrant and lightly golden.
If using hazelnuts: Rub them in a clean kitchen towel immediately after roasting to remove the skins.
Set the nuts aside and allow them to cool completely. Prepare your silicone mat or parchment paper on a cool, flat surface.
Step 2: Create the Caramel (Wet Method)
In the heavy-bottomed saucepan, combine the sugar, water, and salt. Place over medium heat.
Stir gently until the sugar dissolves and the liquid is clear. Stop stirring once the liquid begins to boil.
Allow the mixture to boil without stirring (swirl the pan occasionally) until it changes color. It will turn from clear to light amber, then deepen to a rich, dark brown caramel (reaching approximately 320°F/160°C). Watch carefully, as caramel burns quickly.
Step 3: Combine and Cool
Immediately remove the pan from the heat once the desired caramel color is achieved.
Pour the cooled, roasted nuts into the hot caramel and stir quickly with a heatproof spatula until every nut is thoroughly coated.
Pour the entire mixture onto the prepared silicone mat or parchment paper and quickly spread it thinly.
Allow the praline to cool completely and harden (about 30 minutes). It should be brittle.
Step 4: Finish (Crunchy Praline or Paste)
Once hardened, break the praline slab into large chunks.
To use as crunchy topping: Chop the brittle pieces coarsely with a sharp knife.
To make Praline Paste (Pâte de Praliné): Place the broken chunks in a food processor. Process continuously for 5–10 minutes. The mixture will first become powder, then sand, and finally smooth and glossy as the nut oils are released.
