Respectfully disagree Sneak. Had great meals, good meals, not so good meals here, Italy, Spain and France. Best meals in Europe were in Vienna and Lisbon.
Quality ingredients exist everywhere. The biggest difference IMO is in preparation and that's a personal judgement. Maybe you enjoy how European chefs handle their ingrediants as opposed to American chefs and that's a legitimate preference.
But going to the markets in too many cities to count proved to me - and me alone - that each country has special ingredients and some not so special. For example, France has the best cheese in the world IMO. I think we have the better beef and fish. Veggies are about equal because all depend on unique micro climates.
To say Europe has universally better ingredients is myopic IMO. Yes, they have some better than here and some worse - and that can be said about almost any product, food or otherwise.
No one area of the world has the best of everything.
