Measure 250 grams of raw peanuts and spread them evenly on a baking tray. Roast the peanuts in a preheated oven at 180°C for 10-12 minutes, or until they turn golden brown. Remove from the oven and let them cool.
Grease a large flat tray or a baking sheet with a thin layer of ghee or butter. Set aside.
In a heavy-bottomed pan, add 200 grams of sugar and 60 ml of water. Cook on medium heat, stirring occasionally, until the sugar dissolves and turns into a golden-brown caramel.
Once the caramel reaches the desired color, quickly add the roasted peanuts and 1/2 teaspoon of baking soda to the pan. Stir well to ensure that the peanuts are evenly coated with the caramel.
Immediately pour the peanut-caramel mixture onto the greased tray or baking sheet. Use a spatula or a flat spoon to spread the mixture evenly and flatten it to your desired thickness.
Allow the peanut brittle to cool completely at room temperature. Once it has hardened, break it into pieces using a knife or your hands.
