Straw searing is a cooking technique that briefly sears only the food's surface with a strong flame from burning straw. It is used for dishes such as katsuo tataki.

Reading the bitterness
In the katsuo tataki introduced by Kōchi Prefecture's Fisheries Promotion Division, salt is rubbed into the cut portions of flesh, which are then seared as if smoking them over a fire of straw or miscanthus reed. The guide for doneness is that only the surface is cooked while the inside remains nearly raw. After searing, the fish is immediately dipped in cold water and the moisture quickly drained off. The source gives no values for flame temperature, searing time, or the fish's core temperature.
Handling after searing is not uniform. A separate record of Kōchi Prefecture's food culture reports that whether the dish is served warm or cooled differs between coastal and inland areas. Set alongside the procedure of dipping it immediately in cold water, cooling cannot be determined to be an essential step of straw searing. Both are records of cooking practice, not tests in which people compared differences in aroma, bitterness, or preference arising from the cooling method or the type of fire.
Sources for this overview
Checked for this overview: Supports the fire of straw or miscanthus reed, the guide of heating only the surface while keeping the inside nearly raw, the immediate cold-water treatment, and the limitation that no numerical conditions are given / Supports one official procedure of dipping the fish in cold water immediately after searing and draining off the moisture
Checked for this overview: Supports the regional difference in whether the dish is served warm or cooled, and the limitation that this is not a sensory comparison

How processing and cooking change it (3)
Scope: Katsuo tataki of Kōchi Prefecture, recorded in the Ministry of Agriculture, Forestry and Fisheries' 「うちの郷土料理」 (in translation: "Our Regional Cuisine").
Note: It states: 「風味を出すためにわらであぶるのが良いとされるが、一般家庭ではガスの火であぶることが多い」 (in translation: "searing with straw is considered best for producing flavor, but ordinary households often sear it over a gas flame"). Although it explicitly states that straw searing is considered preferable, the source contains no numerical values for combustion temperature or searing time, nor any of the words bitterness, charring, or savory aroma.
