Chef Tips

Sauce thickness: For a thinner sauce, add a little more broth during step 4c. For a thicker sauce, cook slightly longer, stirring often.


How to cube beef

Place meat on cutting board with the grain running horizontally. 

With long strokes of your knife and as little “sawing” as possible cut meat into steaks approximately 1 inch thick. 

Cut those steaks into strips, about 1 inch wide. Finally, cut the strips into squares as evenly sized as possible.
