Pat dry '1a' (angler) with paper towel and leave it aside for now.
Heat 1 Tablespoon of olive oil on a pan.
Add 1b (garlic) and stir on light heat for 30 seconds. Add angler and heat for 1~2 minutes on medium-high heat while flipping every 30 seconds (until the surface of the fish is cooked).

Add 2 (onion & carrot, lotus root, sauce) and stir on medium heat for 9~12 minutes (until most of the liquid has evaporated).

Optional: add 2 (red pepper) for slightly spicy flavor.
