This was awesome! Cucumber kimchi is my favorite! I already had toasted sesame seeds so I skipped the first step. I also used apple cider vinegar instead because that is what my mom always uses when she cooks Korean food and added a pinch of sugar, or "sweetness" as my mom calls it. It was very easy to make and really tastes like the real thing!
**I just wanted to say that kochujong isn't really a hot sauce, it is hot pepper paste...just thought this might help people who are looking for it
