Add all the ingredients to a food processor or blender and blend until smooth. If all the ingredients won't fit in your food processor, add what you can, pulse it to break it down and gradually add the remaining ingredients.
Taste and adjust seasoning and spice if needed.

Notes
Gochugaru: This is a Korean chili flake. You can find it in an Asian market or order it on Amazon. Start with 2 tablespoons. Taste it and add more depending on how spicy you like it.
Vinegar: Start with 1 tablespoon. Taste it and add more depending on how tangy you like it. If you can find Surig Essig Essenz Concentrated Vinegar, use that. It’s a German brand and really packs a punch.
Serving with noodles: The noodles should be cold! Once cooked, drain and dip in ice water to cool them down. Drain well before mixing with the sauce.
Storage: Keep sauce in an airtight container in the refrigerator and use within 2 days of making.
Freeze: Place sauce in a freezer-safe container and freeze for up to 2 months. Thaw overnight in the refrigerator and use immediately upon thawing.
