Fill a medium saucepan with enough water to boil the groundnuts. Place on high heat and bring to a boil. Immediately the water starts boiling, gently put in the groundnuts, cover and boil for three to five minutes. Turn off the heat and use a colander to strain the groundnuts. Spread the groundnuts over a big tray or baking pan such that there is enough room for each groundnut to dry.
Whisk together the flour, sugar, powdered pepper, black pepper, baking powder, nutmeg and salt in a bowl.
Heat a deep fryer with oil on medium heat. When oil is hot, put in some of the groundnuts. DO NOT CROWD the fryer. Continuously stir till the groundnuts are brown. Remove from the oil and place in a colander lined with paper tissues. The groundnuts gets darker and crunchy when cooling so do not keep them in the fryer for long.
Store in an airtight container for up to seven days
