Introduction

PHOTO

Calling all chocolate lovers! Get ready to indulge in the rich and complex flavors of bittersweet chocolate on January 10, also known as National Bittersweet Chocolate Day. This type of chocolate has a higher percentage of cocoa and less sugar, giving it a more intense and slightly bitter taste. It was first introduced in Europe during the 19th century and has since become a beloved treat for many around the world. Whether you prefer to savor it on its own or use it in your favorite desserts, this day is the perfect excuse to satisfy your sweet tooth with some bittersweet goodness.

TIMELINE

National Bittersweet Chocolate Day Timeline

Early Use of Cacao Beans

The Olmec civilization in Mexico first started to cultivate cacao beans, a key ingredient in chocolate.

Invention of Cocoa Processing

Coenraad Johannes van Houten, a Dutch chemist, invented a hydraulic press to separate cocoa butter from roasted cacao beans, making it easier to produce chocolate.

First Chocolate Bar

The Fry's Chocolate factory in Bristol, England, created the first modern chocolate bar by adding back some of the cocoa butter to the processed cacao.

Invention of Milk Chocolate

Swiss chocolatier Daniel Peter created the first milk chocolate by adding dried milk powder to the chocolate recipe.

Increasing Popularity of Dark Chocolate

Consumer tastes began shifting towards darker, more bitter chocolate, leading to an increase in the popularity of bittersweet chocolate.
