 Colonial goods shops spread only in the 19th and early 20th centuries and brought luxury goods like cocoa, coconuts, rare exotic spices, coffee and (non-herbal) tea to a wider audience.The first wave of foreigners coming to Germany specifically to sell their food specialties were ice cream makers from northern Italy, who started to arrive in noticeable numbers during the late 1920s.With the post-World War II contacts with Allied occupation troops, and especially with the influx of more and more foreign workers that began during the second half of the 1950s, many foreign dishes have been adopted into German cuisine — Italian dishes, such as spaghetti and pizza, have become staples of the German diet.
