From my experience, I tend to notice that in Europe, there is a north/south boundary. Those countries geographically south of the latitude where the AlpsItaly has good large quantity and quality cuisine. Probably tops in the world when it comes to cultural cuisines.
are located (Italy, Spain, Greece, southern France, etc) tend to have cuisines that are zestier and more full of flavour, while countries north of that latitude (UK, Germany, Holland, Scandinavian countries, etc.) tend to have much blander cuisines.
These differences are probably most likely due to climate, as I've indicated earlier (warmer, more temperate Mediterranean climes, accompanied by rich soils, will tend to produce a wider variety of produce and spices). Furthermore, the countries south of the latitude of the Alps also border the regions of the Near/Middle East and North Africa, regions with some of the earliest recorded instances of agriculture in the region, and the home of many ancient civilizations (the ancient Greek civilization, the Roman empire) which have no doubt influenced the cuisines.
