This Vietnamese beef stew (Bo Kho) is such a hearty and comfort soup that will warm up your heart in this cold and windy winter season. I learned how to make this stew a while back from my mom. To me she made the best "Bo Kho" that I have ever tasted. What makes her recipe different from the others is that she concocted her own spices instead of using the pre-mixed "Bo Kho" spices that sold ubiquitously at any Vietnamese supermarket. The flavor of her soup definitely has more depth and very comforting to the palate. This traditional stew is very versatile because you can serve it with rice noodle, with steamed rice or with a nice warm loaf of baguette. I love to enjoy this stew with the crusty baguette for an energy-filled breakfast with a nice cup of Vietnamese coffee while my husband loves it served with rice noodle for dinner. The cooking process may require some simmering time to tenderize the beef and to strengthen the depth of the flavor, but the ending result is well worth it. I hope you, too, will enjoy this hearty stew as much as I do.
