To make peanut butter at home, the basic process involves roasting peanuts and then blending them in a food processor until smooth. Here is a simple recipe outline:

1. Preheat the oven to 350°F (175°C).
2. Spread raw peanuts evenly on a baking sheet and roast them for about 10-12 minutes until lightly browned and fragrant.
3. Let the peanuts cool slightly, then place them in a food processor.
4. Pulse initially to break down the peanuts, then blend continuously. The peanuts will move from a crumbly stage to a dough-like paste, and finally to smooth creamy peanut butter.
5. Add a pinch of salt to taste, and if desired, a bit of oil for creaminess or a sweetener such as honey or maple syrup.
6. Continue processing until the peanut butter is smooth and creamy.
7. Store it in an airtight container, preferably in the refrigerator, for up to a few weeks.

This homemade peanut butter requires just peanuts (raw or dry roasted), salt, and optionally some oil or sweetener. The food processor may need breaks to avoid overheating during blending. This straightforward process yields fresh, creamy, and delicious peanut butter that can be customized in texture and flavor.
