While Columbus had taken cacao beans with him back to Spain,[19] chocolate made no impact until Spanish friars introduced it to the Spanish court.[15] After the Spanish conquest of the Aztecs, chocolate was imported to Europe. There, it quickly became a court favorite. It was still served as a beverage, but the Spanish added sugar, as well as honey, to counteract the natural bitterness.[22] Vanilla was also a popular additive, with pepper and other spices sometimes used to give the illusion of a more potent vanilla flavor. Unfortunately, these spices had the tendency to unsettle the European constitution; the Encyclopédie states, "The pleasant scent and sublime taste it imparts to chocolate have made it highly recommended; but a long experience having shown that it could potentially upset one's stomach," which is why chocolate without vanilla was sometimes referred to as "healthy chocolate." [23] By 1602, chocolate had made its way from Spain to Austria.[24] By 1662, the bishop of Rome had declared that religious fasts were not broken by consuming chocolate drinks. Within about a hundred years, chocolate established a foothold throughout Europe.[15]
