Mamakari Vinegar Pickle: A Complete Guide to the Charm and Preparation of Okayama’s Representative Local Cuisine
“Mamakari vinegar pickle,” known nationwide as a representative local dish of Okayama Prefecture, has a name origin rooted in the saying “so delicious that one would borrow rice (mama) to eat it.” This traditional dish, made from small fish caught in the Seto Inland Sea, is an indispensable part of Okayama’s food culture. This article presents the full appeal of this local cuisine, from its history through preparation methods to ways of enjoying it.
Mamakari: The Small Fish of the Seto Inland Sea that Okayama Boasts
Basic Knowledge of Mamakari (Sappa)
Mamakari is formally called “sappa,” a small fish of the Herring family. With a body length of approximately 10-15cm, it is characterized by a beautiful silvery-white fish body. While called “sappa” in the Kanto region and “harakata” in the Kansai region, in Okayama Prefecture it has long been familiar by the name “mamakari.”
Belonging to the Herring family along with sardines, halfbeaks, and bristletails, it inhabits areas centered around the Seto Inland Sea. In particular, the Seto Inland Sea off the coast of Okayama is known as a prime fishing ground for mamakari, famous as a production area where high-quality mamakari is landed.
Name Origin and Cultural Background
While there are various theories about the origin of the name “mamakari,” the most widely known is the explanation that it means “so delicious that one would borrow rice (mama).” According to the legend, the vinegar pickle of mamakari was so delicious that rice would run out quickly, and one would have to borrow rice from a neighbor’s house, thus giving the dish its name.
This name is not merely an expression of deliciousness but also symbolizes a culture of mutual aid in the regional community of the past and human connection through food. The name reveals how much affection the people of Okayama held for this small fish.
Season and Fishing Period
The best season for mamakari is from October to November. During this period, mamakari becomes fattier and the flesh firms up, making it at its most delicious. Mamakari caught in the autumn Seto Inland Sea have grown by consuming abundant plankton during the summer months, making them highly nutritious with an exceptional flavor.
In Okayama Prefecture, large quantities of mamakari are landed during this peak season, and vinegar pickles are made in households and restaurants. With advances in freezing technology in recent years, it has become possible to enjoy mamakari year-round, but vinegar pickle made with fresh mamakari from the peak season remains incomparably delicious.
History of Okayama Prefecture and Mamakari Vinegar Pickle
History, Origins, and Related Events
The history of mamakari vinegar pickle is ancient, with records suggesting it already appeared on the tables of common people in Okayama during the Edo period. Facing the Seto Inland Sea, Okayama Prefecture has long been blessed with abundant seafood, and particularly developed techniques for processing small fish as preserved foods.
The vinegar pickle method was an important preservation technique in an era without refrigerators. The preservative effects of vinegar allowed freshly caught fish to be stored for long periods, making it a precious source of protein. Mamakari in particular, with its soft bones, becomes even easier to eat when preserved in vinegar, establishing itself as an excellent dish as a source of calcium.
In Okayama Prefecture, there is a tradition of mamakari vinegar pickle appearing on dining tables during autumn festivals and New Year celebrations. Additionally, “mamakari sushi,” a dish featuring mamakari vinegar pickle placed on vinegared rice, is also enjoyed as a local specialty.
Primary Transmission Regions
While mamakari vinegar pickle is eaten throughout Okayama Prefecture, it has been particularly actively produced in coastal areas facing the Seto Inland Sea. In coastal cities such as Okayama City, Kurashiki City, and Tamano City, each household has passed down unique seasoning methods and recipes through generations.
The Okayama Fisheries Cooperative Federation actively promotes mamakari, and it is widely offered at local supermarkets, izakayas, and restaurants. In recent years, distribution channels outside Okayama Prefecture have also expanded, and it has become increasingly recognized nationwide as an Okayama local specialty.
How to Make Mamakari Vinegar Pickle
Ingredients (Serves 4)
Main ingredients:
- Mamakari (sappa): 12-16 fish (approximately 400g)
- Salt: as needed (for preparation)
- Vinegar: 200ml
- Sugar: 3-4 tablespoons
- Mirin: 2 tablespoons
- Soy sauce: 1 teaspoon (to taste)
- Fresh ginger (julienned): 1 piece
- Red chili pepper (sliced into rings): 1 pepper
※The sweet vinegar ratio varies by household and region. Using store-bought pickled vegetable vinegar makes preparation even easier.
Preparation Method
Initial Preparation
- Preparing the mamakari: Carefully remove the scales from the mamakari. Remove the head and open the belly to remove the internal organs. Wash thoroughly under running water and clean away blood and other impurities.
- Splitting: Using a knife, cut along the center bone and fillet the fish into three pieces. If small bones are a concern, remove them with tweezers, though they will soften from vinegar pickling and can be left intact.
- Salt curing: Sprinkle salt on the split mamakari and let sit for approximately 30 minutes. This removes excess moisture and firms up the flesh.
- Rinsing: Rinse away the salt under running water and thoroughly pat dry with paper towels.
Preparing the Sweet Vinegar
- Making the sweet vinegar: In a pot, combine vinegar, sugar, mirin, and soy sauce and heat gently until the sugar completely dissolves. Remove from heat and allow to cool to room temperature.
- Preparing seasonings: Julienne the ginger and remove seeds from the chili pepper before slicing into rings.
Pickling
- Pickling: Arrange mamakari in a storage container, scatter ginger and chili pepper, and pour in the cooled sweet vinegar, ensuring the mamakari is completely submerged.
- Refrigerate: Cover and refrigerate for at least 1 day, preferably 2-3 days. The longer it pickles, the more the flavors infuse and the softer the bones become.
Cooking Tips
- Freshness is key: Mamakari spoils quickly. Use the freshest fish available.
- Salt balance: If salt curing takes too long, the fish becomes tough. Aim for 30 minutes to 1 hour.
- Sweet vinegar ratio: The proportions vary by household throughout Okayama Prefecture. Adjust the sugar amount to your preference.
- Pickling time: While edible after 1 day, pickling for about 3 days softens the bones completely and allows flavors to meld well.
- Storage period: Can be stored in the refrigerator for approximately 1 week.
