Does roasting nuts make a difference?
Yes, roasting nuts increases a nut's flavor, making it a more assertive ingredient in terms of flavor. Thanks to a process called the Maillard Reaction, named after the French chemist Louis Camille Maillard, a complex reaction occurs when proteins and sugars are heated together. The molecules break down into hundreds of flavor compounds, forming a brown color and increasing the complexity of taste. This same reaction is also responsible for the transformation that takes place when meat is browned and coffee beans roasted.
It's important to note that there is very little difference between the nutrient compositions for raw versus roasted pistachios as evidenced in the Pistachio Health tree nut comparison chart.
