The provided reference describes how to toast sesame seeds and turn them into a powder, but it does not explain how to turn white sesame seeds black. Therefore, using natural methods, you can't directly make white sesame seeds black. The black color comes from the type of sesame seed, not a process you can apply to white seeds.
To obtain black sesame seeds, you must purchase black sesame seeds.
If you simply want the flavor of black sesame seeds, you could try the following workaround, though the result will not look the same:
- Toast white sesame seeds: Lightly toast the white sesame seeds in a dry pan over medium heat for 1-2 minutes, until they are lightly golden and fragrant. Be careful not to burn them.
- Add a small amount of activated charcoal powder: In a bowl, mix the toasted sesame seeds with a very small amount of food-grade activated charcoal powder. Start with a tiny amount (e.g., 1/8 teaspoon per cup of sesame seeds) and gradually add more until you reach your desired color intensity. Be cautious, as too much can make the sesame seeds taste bitter.
- Mix thoroughly: Ensure the charcoal powder is evenly distributed throughout the sesame seeds.
Important Notes:
- Using activated charcoal only changes the color and doesn't replicate the exact flavor profile of black sesame seeds.
- Always use food-grade activated charcoal.
- Be mindful of the amount of activated charcoal you use, as excessive consumption can have side effects.
In summary, you cannot truly "make" white sesame seeds black. You must purchase black sesame seeds if you want the genuine article. The charcoal method can provide a visual approximation, but not a flavor match.
