I suppose this is true of any seeds used as spices, but coriander seeds are perfect because they are little and round and hard, and so, when you eat something with coriander seeds in it --
You will be chewing along on a delicious mouthful, and suddenly your teeth will hit on a seed and pop it open, and all the flavor that was locked in the seed even through cooking will make a little
!burst! into your mouth.
So you should eat them because they are so much fun to eat.
