DescriptionShe's popular in Poland! Thousands crowd the marketplace in Gdansk to catch a glimpse of the Duchess as she and Wills toast their new fans with a traditional liqueur made from flakes of gold.The Duchess of Cambridge was taken aback when she tried a 'very strong' local Polish tipple today - as she and husband William received a rapturous welcome in the city of Gdansk.Kate, 35, and William are on the second day of their tour of Poland and, after an emotional visit to a concentration camp on Tuesday morning, they moved on to a medieval market in Gdansk's historic old town where they sampled local delicacies including Goldwasser, a traditional liqueur with flakes of gold, and pierogi dumplings.'It is very good, very sweet,' William said after he downed the shot in one. 'And very strong,' Kate added as she recovered from downing the 40 per cent proof liqueur. Thousands of locals lined the central market square as the royals arrived, and during their visit today the couple were given a live demonstration of amber processing before trying out local delicacies. As the royal couple emerged from the town hall to the strains of Handel's 'Zadok the Priest' - played at every English monarch's coronation since King George II in 1727 - the crowds cheered enthusiastically. The Duchess looked radiant in a white floral two-piece from Erdem as she greeted crowds as the music by Capella Gedanesis, a world renowned ensemble, played in the background.The crowds, ten deep, were held back amid tight security behind steel barriers and the royal couple flanked by close guarded maximum security. William and Kate were welcomed in the Arthus Court in the very heart of Gdansk. Amid cheering and classical music the Duke and Duchess wandered through the Long Market with the Fountain of Neptune, a symbol of Gdansk. They chatted to local tradesmen including amber expert Zbligniew Strzelczyk, owner of the Styl Gallery Gdansk, a city famed for the stone since Medieval times. The craftsman said: 'They were very interested in the trade. Prince William asked about where the amber is found and I told him to 10 per cent is washed up on beach. I gave them two chunks of amber, one with an ant and two leaves inside and another with a little fly and air bubbles. They seemed delighted.'They couple then downed glasses of Gdansk liqueur at the next stall, Goldwasser (golden water), a strong root and herbal liqueur which has been produced since at least 1598.Damian Robakowski of Pod Lososiem restaurant said: 'They both seemed to love it. It is very powerful.'
