Latinos LOVE Flan. Flan is a creme caramel custard made in many Spanish countries, but also popular in Europe and Asia. Flan is one of the richest desserts anyone can eat. It has a sugary creamy taste to it. It is so soft and savory that one spoonful literally dissolves in your mouth where you get to taste the sugar, milk, caramel and vanilla all in one delicious treat. Is a flavorful slice of heaven.
