As you probably already know, cocoa is produced in countries in a belt between 10ºN and 10ºS of the Equator, where the climate is appropriate for growing cocoa trees. Cocoa plants respond well to relatively high temperatures, between 18 - 32ºC (64 - 90ºF).
The natural habitat of the cocoa tree is in the lower layer of evergreen rainforests, and climatic factors, particularly temperature and rainfall, are important in encouraging optimum growth.
So, no need to worry about reindeer milk chocolate with notes of smoked salmon: there is no plan for a Chocolate from Alaska!
Happy April Fool's Day!
