Milk Caramel Chocolate Biscuit for Mental Performance 
 
Made of the delicious and unique Argentine Dulce de Leche. 
 
"Dulce de leche" is a confection from Argentina prepared by slowly heating sweetened milk to create a substance that derives its flavour from the Maillard reaction, also changing colour, with an appearance and flavour similar to caramel.
 
 Dulce de Leche is the Spanish for "candy [made] of milk" or "caramel".
