Die Schaumküsse aka Schokoküsse are a popular thing for kid’s birthdays in Germany and, subsequently, are nostalgic for many adults. :) They’re also very tasty. They were first introduced in industrial numbers in 1920, although their first mention dates back to 1829. They’re sold at supermarkets and sometimes bakeries all year long and also appear fresh on fairgrounds. Pressed between 2 halves of a bun, they’re referred to as a Matschbrötchen (mud roll/squished bread roll) and eaten by children. The inside is sweet egg white foam - the consistency is quite fluffy rather than sticky or gooey like marshmallows. They were first known under the names Mohrenkopf (literally “moor’s head”) or Negerkuss (literally “negro's kiss”), but these names had to go due to increased political correctness... So most companies changed their official name to the more neutral Schokoküsse (chocolate kisses) or Schaumküsse (foam kisses). In German-speaking Switzerland they’re still sold as Mohrenkopf. In the French-speaking parts as well as France, they’re known as Têtes Choco (chocolate heads). Read about what similar concoctions are called in other countries here.
