Roast ajwain seeds on low heat in a dry pan, stirring constantly, until fragrant and slightly darker in color, typically 2-3 minutes. Avoid high heat and prolonged roasting to prevent bitterness.
Roasting ajwain seeds enhances their flavor and aroma, making them more potent for culinary and medicinal uses. However, over-roasting can lead to a bitter taste. Here's a step-by-step guide to roasting ajwain properly:
Prepare a Pan: Use a heavy-bottomed pan or skillet. This helps distribute heat evenly and prevents hot spots that can burn the seeds.
Low Heat: Place the pan on the stovetop and set the heat to low. Patience is key here. High heat will quickly burn the ajwain.
Add Ajwain: Add the ajwain seeds to the dry pan. There's no need to add oil or any other ingredient.
Constant Stirring: Continuously stir the ajwain seeds with a spatula or spoon. This ensures even roasting and prevents burning.
Monitor Color and Aroma: Roast the ajwain until it becomes fragrant and slightly darker in color. This usually takes about 2-3 minutes. Be careful not to let them turn too dark.
Remove from Heat: Once roasted, immediately remove the ajwain from the hot pan and transfer it to a cool plate or bowl. Leaving it in the hot pan will continue the cooking process and potentially lead to bitterness.
Cool Completely: Allow the roasted ajwain to cool completely before storing it in an airtight container.
Trust your nose! The aroma of the ajwain is the best indicator of doneness. If you start to smell a burnt or acrid odor, remove the pan from the heat immediately, even if the seeds haven't darkened significantly. It's better to under-roast slightly than to over-roast and end up with bitter ajwain.
