Hello from Pittsburgh, Pennsylvania

First I would like to thank you for having this website. My daughter became more interested in the Korean culture bc of BTS. And now we are taking Korean language lessons and learning how to cook. One thing I would like to know is whether all Korean dishes need to be spicy. I love the taste of many of the ingredients, but I’m not good with spicy foods. Is the best way around that to just play around with using smaller portions of the hot pepper until I find an amount that works for all of us in the family? Thanks all! Erika
