1/2tspfinely chopped green onion(heaped), – You can add more if you like.
1green or red chili(optional), I didn’t use this, but if you want to make it extra spicy sauce, you can add it.
For base sauce
Mix these in a bowl and stir until the sugar dissolves. (I normally prepare the sauce one day before I'm making the pancakes and keep it refrigerated. The sugar will be dissolved overnight even if you don't stir it. You can also lightly boil the sauce over low heat just until the sugar dissolves to quicken the process. It will have to be cooled down before use.)
For kids friendly (non-spicy) version
Mix 7 Tbsp of the base sauce and sliced onion pieces. (Even if you don’t eat the onion slices, still add them as they add a nice extra flavour.) Serve as you need.
For spicy version
Mix remainder (7 Tbsp) of base sauce and the rest of the optional ingredients. Mix them well. (Frankly speaking, this combination isn’t that spicy to my tastebuds. Maybe occasional kicks near the end. Adjust the spiciness with Korean chili flakes and/or green/red chili as suggested above according to your desire.) Serve as you need.
