An entirely natural liqueur that is made from brandy, egg yolk, sugar and vanilla. No artificial preservatives or thickeners are used. Advocaat is said to have originated from Dutch sailors who obtained an avocado drink sourced in the Dutch Antilles during the 17th century. On their return to the Netherlands they demanded more of the drink that they has developed a taste for. Eventually a similarly yellow coloured drink was formulated but in this case it included egg yolk and not avocado.
