I stuck fairly close to the recipe. I have asian pears available, and happily used them. I did use the mustard oil that came with the noodles, but made my own broth and took the juice from yeolmu mulkimchi also from this site. Everything came out superbly!
The recipe for mulnaengmyeon (물냉면) is here.
ahh! I’m making naengmyeon for lunch today. Irresistible photo!
