I started cooking Korean food about four years ago. At that time, I had no idea what I was doing, even though I live with my MIL who is a Korean cook. My MIL cooks by taste, meaning she never uses measurements for anything. I found it really hard to learn from her and the fact that I could barely speak Korean didn't help so I turned to the Net.
The first website I found was Maangchi. It seemed amazing and had so many followers. The first recipe I tried - Panfried Tofu with Spicy Sauce - turned out great and I still use it today. I was excited to start cooking Korean food so I tried other Maangchi recipes but none of them tasted right. When I served my MIL Spicy Beef and Vegetable Soup she spit it out saying it was 맞없어 (not delicious!). She had to add various ingredients to make it taste right and since then pretty much every recipe I've tried from the Maangchi website just doesn't taste right.
I wonder then why there are so many followers on Maangchi's site? Maybe they just have no idea what Korean food should taste like.
On the other hand, Aeri's Kitchen is excellent. Most of the recipes on the site turn out pretty good. The first time I made Korean Curry Rice, my husband's eyes widened in amazement, he couldn't believe my cooking could taste so good^^ . I use certain Aeri recipes all the time such as the Seaweed Soup, Spinach Bean Paste Soup, Tuna Kimchi Jiggae, Clay Pot Bulgolgi and Tuna Pancake.
