The origin
The history of biscuits and cookies dates back quite long. The biscuits were first baked in Persia in the 7th Century BC. However the modern biscuit came into origin much later in France during the 14th Century. The name originates from Latin word bis cotum which means baked twice.
The biscuits are hard and dry. The cookies are a much modern invention. We find the first reference of preparation of cookie in the Dutch bakeries. Referred to as ‘koekje’, these were small round cakes which were used by the bakers to find if the oven has reached the right temperature. The most common and modern version of chocolate chips cookie came into origin in 1937. The American chocolate chips cookies still remains the most popular and common among these cakes.
