Geum-Young (Hong Ri Na) goes to talk to Jang-Geum (Lee Young Ae) who is making her fermented soybean pastes. Geum-Young tastes one of the samples and asks how it doesn’t stink like it usually does. Jang-Geum tells her it’s because she used coal to kill of the smell. Then Geum-Young goes back to the kitchen and asks her mom if she can make the next meal for the princess. So she use the coal to remove the smell from the rice and the princess eats the whole thing. It’s because she added the same ingredient Jang-Geum used to kill of any smell, as it turns out princess was turned off by the smell of food. The whole Royal Kitchen gets rewarded and all the supervisiors are praising Geum-Young. But Keum-Young mentions she was inspired by Jang-Geum’s method.
