Optional Additions for More Depth

Essential Equipment
Before you start cooking, having the right kitchen tools on hand makes the process smoother.
- Saucepan or deep frying pan – To cook and simmer the sauce evenly.
- Whisk or wooden spoon – Helps blend the ingredients smoothly.
- Blender (optional) – If you prefer a super silky, restaurant-style curry sauce.
- Fine mesh strainer (optional) – To remove any solid bits for an ultra-smooth texture.
Step-by-Step Cooking Instructions
Making katsu curry sauce with coconut milk is simple and rewarding. Follow these steps for a perfectly balanced, creamy sauce:
1. Sauté the Aromatics
- Heat 2 tablespoons of oil in a saucepan over medium heat.
- Add chopped onions and cook until soft and golden brown (about 5 minutes).
- Stir in garlic and ginger, cooking for another minute until fragrant.
2. Add the Spices
- Sprinkle in curry powder, turmeric, and garam masala.
- Stir continuously for about 30 seconds to toast the spices and release their aroma.
3. Thicken the Base
- Sprinkle flour or cornstarch over the mixture and stir well.
- This step ensures the sauce thickens later.
4. Pour in the Liquids
- Slowly add coconut milk and broth, whisking to prevent lumps.
- Stir in soy sauce and optional honey or sugar for balance.
5. Simmer and Adjust Consistency
- Reduce heat to low and let the sauce simmer for 10-15 minutes, stirring occasionally.
- If too thick, add more broth; if too thin, let it cook longer.
6. Blend for Smoothness (Optional)
- For an ultra-smooth texture, blend the sauce using an immersion blender or regular blender.
- Strain through a fine mesh sieve if needed.

Fine-tuning your katsu curry sauce ensures the perfect taste. Here’s how to balance the flavors:
| Issue | Solution |
| Too spicy? | Add more coconut milk or a teaspoon of sugar. |
| Too mild? | Increase curry powder or add a pinch of chili flakes. |
