Cafe Bombon was made popular in Valencia, Spain, and spread gradually to the rest of the country. It might have been re-created and modified to suit European tastebuds as in many parts of Asia such as Malaysia, Thailand and Singapore the same recipe for coffee which is called "Kopi Susu Panas" (Malaysia) or "Kafe Ron" (Thailand) has already been around for decades and is very popular in "mamak" stalls or "kopitiams" in Malaysia. A café bombón, however uses espresso served with sweetened condensed milk in a 1:1 ratio whereas the Asian version uses ground coffee and sweetened condensed milk at the same ratio. For café bombón, the condensed milk is added to the espresso. For visual effect, a glass is used, and the condensed milk is added slowly to sink underneath the coffee and create two separate bands of contrasting colour - though these layers are customarily stirred together before consumption. Some establishments merely serve an espresso with a sachet of condensed milk for patrons to make themselves.
