The secret to this rich Japanese-style demi-glace is a clever shortcut using tonkatsu sauce, skipping the hours of simmering required for traditional French stock. You'll get a deep, savory flavor profile from a blend of red wine, tomato passata, and a splash of soy sauce. It's an essential component for classic yoshoku dishes like omurice or Hayashi rice. Keep a batch in the fridge, and you'll always have a complex, restaurant-quality sauce ready to elevate your next meal.
