Sweet-tasting hot chocolate was then invented, leading hot chocolate to become a luxury item among the European nobility by the 17th century. Even when the first Chocolate House (an establishment similar to a modern coffee shop) opened in 1657, chocolate was still very expensive, costing 50 to 75 pence (approximately 10-15 shillings) a pound (roughly £45-65 in 2016). At the time, hot chocolate was often mixed with spices for flavor; one notable recipe was hot chocolate "infused with fresh jasmine flowers, amber, musk, vanilla and ambergris." In the late 17th century, Sir Hans Sloane, president of the Royal College of Physicians, visited Jamaica. There, he tried chocolate and considered it "nauseous", but found it became more palatable when mixed with milk. When he returned to England, he brought the recipe with him, introducing milk chocolate to England. The aristocratic nature of the drink led to chocolate being referred to as "the drink of the gods" in 1797.
