Once he told me, I could see it: tiny flecks of minced rosemary embedded in the linguini itself. Brilliant! I suspect that whole rosemary was also simmered in the sauce and then removed before serving, but including it in the pasta itself ensures consistent seasoning inside and out.
I don’t know why it never occurred to me to try this before! It would be so easy to add a few tablespoons of minced herbs straight into the dough while mixing it. Not so much that the pasta turns green, but just enough to add a little punch of flavor.
I’ll definitely be experimenting with this in my next batch of pasta. Have you ever done this?
