How can I use Rosemary bulbs in cooking? I pulled out a rosemary plant today and found a number of bulbs amongst the root system.   Can these be used for cooking, such as with a roast lamb?  How?

I also have lots of leaves, so if the bulbs are no good I don't need to use them but I thought it was interesting to try.
I don’t know what you dug up, but rosemary doesn’t have bulbs so do not eat this!

For plant id questions (which is outside the scope of this site), I recommend our sister site Gardening SE.
