Which food things make a difference, which don't?

[El Diablo]

I'll give my opinions on some of these after a few responses. Feel free to add your own things:

Fresh herbs v. dried herbs

Ground pepper from peppercorns/grinder v. ground pepper from shaker

Sea salt v. regular salt

Fresh chili peppers v. powder

Specialty (virgin/extra virgin) olive oil v. grocery store (virgin/extra virgin) olive oil

Specialty balsamic vinger v. generic balsamic vineger

Organic fruit/veg v. regular

Farm/Farmer's market fruit/veg v. grocery store

Premium fresh pasta v. premium dried pasta

Organic meat v. regular

Butcher meat v. grocery store

Free range poultry v. regular

Grass fed beef v. grain fed beef

Farmed salmon v. wild salmon

I'm not looking for essays on any of this stuff or answers for everything. I'm just looking for pointers from those of you who cook a lot like "the difference in using fresh herbs v. dried is HUGE" or whatever little changes in ingredients make dishes WAY better.
