Yes, some people perceive a subtle bitterness in cumin seeds.
While the dominant flavor profile of cumin seeds is often described as earthy, warm, and slightly nutty, a secondary characteristic for some palates is a slight bitterness or a hint of citrus. This bitterness is generally not overwhelming but can be noticeable, especially if a large quantity of cumin is used or if the cumin is toasted too aggressively.
It's important to note that individual taste perception varies. What one person perceives as bitter, another may not. Factors such as the freshness of the cumin, the quality of the seeds, and the cooking method can all influence the final flavor. Roasting cumin seeds, for example, can intensify both their nutty and potentially their bitter notes.
