Retain More Moisture: Browning the chuck steak as a whole retains more moisture due to less surface area.
Brown Faster & Better: Since maillard reaction excels in a dry and high heat environment, the chuck steak will brown faster and better compared to cubed stew.
Richer & Flavorful: The caramelized flavors from browning results in a richer & more flavorful dish.
2. Can I use other beef cuts for this recipe?
Chuck roast is one of the most suitable cuts for pressure cooking. For optimal result, choose one that is well marbled!! This is very critical.
