In a summertime, Korean people enjoy special food for their healthy. It known with samgyetang(삼계탕, ginseng chicken soup). 'Gye' mean 'Chicken' in a word in Korean. When I was young, I had lots of chicken soup in summer time and it still doing. But trend is changing by young generation. They love cold dish in hot summer time. They said 'Hot food in summer time?' No way!'. They love Chogyeguksu (Cold noodle dishe)
I said 'gye' mean chicken, and 'cho' mean 'sour'. We make sour taste by mustard, and vinegar. It's sweet and sour soup by chicken broth. When you try this noodle, you will addicted it!
