How I cook this at home

I keep this recipe practical for everyday cooking: clear steps, linked ingredients, and small notes from my kitchen so you can make it realistically in Germany too.

My notes for this recipe

This tonkatsu sauce recipe is inspired by the Japanese version for the tonkatsu I introduced earlier. In Korea, we usually purchase pre-made tonkatsu sauce rather than making it at home, as it's readily available due to Japan's proximity. There are also Korean-produced tonkatsu sauces. However, if you’re in Germany, you can easily find Worcestershire sauce, which makes it simple to create your own version of tonkatsu sauce.

Finding the ingredients

You can open unfamiliar ingredients directly from the list. Many Korean pantry basics are easiest to find in Asian grocery stores or online, while fresh ingredients can often be handled more flexibly.

Quick tips

  • Read the ingredients and steps once before you start.
  • Prepare the sauce, vegetables, and toppings first so cooking feels calmer.
  • Adjust the final flavor gently with soy sauce, salt, sugar, or sesame oil.

Instructions

  1. Combine the ingredients:

    • In a pan, add all ingredients except the cornstarch slurry. Stir well while bringing the mixture to a boil.

  2. Thicken the sauce:

    • Once it starts boiling, reduce the heat and slowly add the cornstarch slurry while stirring continuously. Stir until the sauce thickens.

That's it—your delicious tonkatsu sauce is ready! Pour it generously over your fried tonkatsu to enjoy an authentic taste. 😊
