Earl of Sandwich risked health with frozen chocolate delight

In 1668, the Earl of Sandwich collected recipes for chocolate, a treat just introduced to England believed to be "unwholesome." His iced chocolate recipes are a highlight of a paper by Dr Kate Loveman of the University of Leicester entitled The Introduction of Chocolate into England: Retailers, Researchers, and Consumers, 1640–1730.

The paper, published in the Journal of Social History, includes the earl's own recipes including one for a chocolate dessert:

Prepare the chocolatti [to make a drink]… and Then Putt the vessell that hath the Chocolatti in it, into a Jaraffa [i.e. a carafe] of snow stirred together with some salt, & shaike the snow together sometyme & it will putt the Chocolatti into tender Curdled Ice & soe eate it with spoons.

Chocolate, at the time, was believed to cause insomnia, excess mucus, and hemorrhoids, as well as damage to the stomach, heart, and lungs.
