Whether chive blossoms with seeds are tasty or not is more a matter of personal taste preference. If you like your food chewy and slightly hard, then you may find chive blossoms with seeds delicious. But if you don't like that texture, then you may find it unpalatable.
It is important to note that chive blossom with seeds has the potential to have a somewhat bitter flavor. If you don't like the bitter flavor, you can reduce the bitterness by soaking the chive blossoms with seeds for a little while and then cooking them. In addition, when choosing chive flowers, you can try to choose seedless ones so that the taste will not affect the eating experience.
In summary, whether chive blossom with seeds is good or not mainly depends on your personal taste preference. If you like chewy food, then you may find it tasty. But if you don't like a slightly harder texture, then it may not be quite right for you.
