Wonderful liqueur. Sweet tortilla chip. Buttery. Notes of caramel. Yes to the oily feels but also may just be the density from the sugars added (think like the viscosity of simple syrup) I drank this after drinking the same brand‘s whiskey, Abasolo. Kind of feel like this is just a sweetened version of that whiskey. May or may not be true but i still enjoy this liqueur. Made a margarita and subbed this for cointreau and enjoyed it a lot! would definitely pair it with an earthy or vegetal tequila/mezcal
