The Origins Of Katsu Sauce

Katsu sauce, or tonkatsu sauce, has its origins in British Worcestershire sauce. When curry was introduced to Japan by the British in the Meiji era, it sparked a trend of Western cuisine that included the concept of cutlets. The Bull-Dog brand of tonkatsu sauce was born and became a popular condiment for tonkatsu, a deep-fried pork cutlet dish.

The sauce is made by stewing vegetables and fruits, then mixing in vinegar and sugar, salt, and spices. While the sauce has its origins in English Worcestershire sauce, the flavor was changed to better suit the taste of the Japanese people. The primary ingredients in Japanese sauce are vegetables and fruits, to which vinegar and many spices are blended. This had the effect of deepening the richness and increasing the appetite. Japanese tonkatsu sauce uses a lot of vegetables and fruits like tomatoes and apples, which make it a highly viscous sauce well suited for deep-fried foods, without getting them greasy or soggy.

The Bull-Dog brand was the first to invent and introduce tonkatsu sauce in Japan. Oliver Sauce is another brand that produces tonkatsu sauce on the western side of Japan. Oliver’s sauces are not commonly available at the eastern Japan, so their shop is a good chance to experience the taste of tonkatsu sauce preferred in western side of Japan.

How Katsu Sauce Is Made

Making katsu sauce is a simple process that can be done in just a few minutes. To make the base of the sauce, you’ll need to combine Worcestershire sauce, ketchup, and soy sauce in a bowl. This will form the foundation of your katsu sauce.

From there, you can add other seasonings like garlic and ginger to enhance the flavor. If you prefer a traditional recipe, you can also add oyster sauce to your katsu sauce. However, if you’re not a fan of oyster sauce, it’s perfectly fine to leave it out.

To make tonkatsu sauce, start by simmering the vegetables and fruits together in a pot until they become soft. Once they’ve cooked down, strain the mixture through a sieve to remove any solids. Then, add soy sauce, vinegar, and sugar to the liquid and stir well.

Finally, add the spices to the mixture and stir until everything is well combined. You can adjust the seasoning to your liking by adding more sugar or spices as needed.

While making tonkatsu sauce from scratch may be time-consuming, it’s worth it for the rich and complex flavor it adds to your dishes. However, if you’re short on time or don’t have access to all the necessary ingredients, store-bought katsu sauce is a great alternative.
