STEP 1/8
Carefully examine each leaf of lettuce, wash it two or three times, and soak it in vinegar water for about 10 minutes.
STEP 2/8
Drain the washed lettuce by standing it in a basket
STEP 3/8
Cut the half of the onion into big pieces.
STEP 4/8
Cut 5 cheongyang peppers sideways.
STEP 5/8
Add half a cup of sugar, half a cup of water, half a cup of soju, and half a cup of dark soy sauce and boil it once.
STEP 6/8
Once it boils, add half a cup of vinegar. If you add vinegar and boil it from the beginning, the vinegar scent disappears. So boil the soy sauce water and add vinegar at the end.
STEP 7/8
Put the washed and drained lettuce, sliced onions, and Cheongyang red pepper in a boiled pickled sauce and hold your breath. If you put lettuce in a container to put it in from the beginning and pour the pickle sauce, it may be inconvenient to put it in a too large container and change it back to a small container if you die, so put lettuce in a boiling pot and put it in the right container if you die.
STEP 8/8
Pickled lettuce is done. Make sure to eat it within a few days by doing the requirements little by little.
Lettuce doesn't get soft even if it's swollen when the pickles are hot.
You can pour it when it's hot and hold your breath.
