I was just in my garden looking at all the parsley seeds. Collected the brown for reseeding in other parts of my property, and I ate some of the fresh ones. Nice flavor, like the leaves but milder. Then I looked up whether fresh parsley seed is safe to eat. The answer is in pretty extreme moderation. Like less than a teaspoon in a recipe. They have two chemicals that can cause liver and kidney damage. So please use caution, and look things up before using something different or unusual (like parsley seeds).
