Complete Guide to Gomadashi | How to Make, Eat, and History of Oita Prefecture Saiki City’s Local Cuisine

Gomadashi, a local dish from Oita Prefecture, is a superb seasoning created by abundant seafood and traditional manufacturing methods—a hidden gem known by those in the know. In the local area, this flavor naturally graces dinner tables every day, characterized by a deep umami and fragrance that you won’t forget once you taste it. This article provides a comprehensive explanation of gomadashi from its history to preparation methods and applications, covering every angle.

What is Gomadashi? A Traditional Seasoning from Saiki City, Oita Prefecture

Gomadashi is a local dish that has been cherished since ancient times in coastal areas along Bungo Channel, centered on Saiki City in Oita Prefecture. It is known as a versatile seasoning made by roasting white fish such as Japanese sandeel and flying fish, then grinding them together with roasted sesame seeds, soy sauce, mirin, and other seasonings.

Basic Characteristics of Gomadashi

The greatest characteristic of gomadashi is the profound depth that emerges from the exquisite harmony between the umami of fish and the fragrance of sesame. It comes in paste or sprinkle form, and can be enjoyed by placing it on warm rice or dissolving it in udon or somen soup broth.

The main ingredients are as follows:

• White fish (Japanese sandeel, flying fish, horse mackerel, etc.)
• Roasted sesame (white sesame is common)
• Soy sauce
• Mirin
• Sugar
• Other seasonings (varies by household and manufacturer)

History and Cultural Background of Gomadashi

A Crystallization of Wisdom Born in a Fishing Town

The origin of gomadashi lies in the fishing towns of Saiki City facing Bungo Channel. Bungo Channel, known as a prime fishing ground where warm and cold currents meet, has yielded diverse varieties of fish.

Japanese sandeel in particular was valued as a raw material for processed fish products like kamaboko due to its soft flesh and numerous small bones, but was difficult to eat as is. Fishermen developed a cooking method to enjoy this fish deliciously without waste—roasting it, shredding it, and grinding it together with sesame.

Its Role as Preserved Food

In times without refrigeration, gomadashi was also an important preserved food. By roasting fish to remove moisture and adding salt to increase preservation, it was utilized as portable food for fishing expeditions and as a seasoning to enrich daily dining tables.

Food Culture Rooted in the Community

In Saiki City, unique gomadashi recipes are passed down in each household and cherished as “grandmother’s taste.” There are subtle differences in the type of fish used, the amount of sesame, and the proportions of seasonings, so each household has its own distinctive flavor.

Traditional Method for Making Gomadashi

Required Ingredients (for convenient portions)

• Japanese sandeel or flying fish: 500g (filleted into three pieces)
• White sesame seeds: 200g
• Soy sauce: 4 tablespoons
• Mirin: 3 tablespoons
• Sugar: 2 tablespoons
• Salt: 1 teaspoon

Basic Manufacturing Process

1. Fish Preparation

Fillet the Japanese sandeel or flying fish into three pieces and carefully remove the bones. This step is particularly important as remaining small bones will negatively affect texture.

2. Roasting the Fish

Slowly roast the fish flesh over medium heat. Once the surface is browned and cooked through, fragrance and preservation quality increase. Be careful not to over-roast as this can develop bitterness.

3. Shredding the Flesh

Finely shred the roasted fish flesh. While doing so, carefully confirm there are no remaining bones.

4. Roasting the Sesame

Roast white sesame seeds in a frying pan until fragrant. The key is to roast over low to medium heat while constantly stirring to avoid burning.

5. Grinding in a Mortar

Place the roasted sesame into a suribachi mortar and grind until about halfway through. Rather than making it completely paste-like, the traditional method preserves some sesame texture.

6. Adding Fish and Seasonings

Add the shredded fish flesh and seasonings (soy sauce, mirin, sugar, salt), then grind further in the mortar. Continue mixing until everything is uniform and becomes a moist, paste-like consistency.

7. Flavor Adjustment

Taste and adjust with soy sauce or sugar. You can make it sweeter or saltier according to household preference.

8. Storage

Place in a clean storage container and refrigerate. If stored properly, it can be enjoyed for about one week.
