Mark takes you through the key ingredients to make filipino leche flan, a dessert that travelled from Spain to different Spanish colonies around the world including the Philippines. The filipino version varies from the Spanish 'milk flan' as there is an added richness and indulgence with the addition of condensed and evaporated milk which came about when the Americans introduced canned dairy goods into the country which played to the filipino sweet tooth.
Caramel - Mark uses a combination of sugar and water to make a wet caramel, which is generally more straight forward to make than dry caramels as it's less likely to burn. Dry caramel just uses sugar whereas with a wet caramel, you also add water which creates a caramel with a stronger flavour since the water needs more time to evaporate giving the caramelisation process more time to take place.
Condensed & evaporated milks - these two canned milks have similar production techniques but condensed milk has sugar added to it as part of the process which makes it thicker and sweeter and it also lasts longer as sugar helps with preservation. You can make the leche flan completely from condensed milk but cutting in some the evaporated milk makes it a little less indulgent and helps to lighten the dish overall.
Egg yolks - egg whites can be a useful ingredient for building mortar as a binding ingredient as it makes it more durable. When the Spanish colonists came to all these different countries and converted them to catholicism, they went on a big building spree of churches and monasteries which required a lot of mortar and egg white. So with the leftover yolks people were able to make desserts like leche flan.
Latik - tagalog term for coconut curds, when you boil coconut milk it'll at some point separate out into the solids (the curds) and oil but if you allow the coconut cuds to cook in that oil it becomes brown and crispy and that's latik. Take it out and dry it becomes crumbly and crunchy. Adds texture to the top of the flan and philippinises the dish more
