Miso — Shiro (White / Sweet Miso)
What it is
The pale, sweet, short-fermented end of the miso spectrum — ivory to light tan, smooth, and high in rice koji relative to soybean. Saikyo miso of Kyoto is its most refined expression.
How it's made
Steamed soybeans are mashed and combined with a large proportion of kome-koji (rice inoculated with Aspergillus oryzae mold) and a relatively low dose of salt, then fermented only briefly — weeks to a few months. The abundant koji and short cure leave residual sugars, hence the sweetness and pale color.
Flavor profile
Mild, sweet, mellow, and creamy, with gentle umami and low salt. The most approachable miso, lacking the funk of darker types.
Culinary uses
Light miso soups, saikyo-yaki (fish marinated in sweet white miso, mirin, and sake), dressings, glazes, and desserts. Its sweetness makes it the pastry-and-marinade miso.
Regional variations
Kyoto's Saikyo style is the benchmark sweet white; other regions make their own light misos with varying koji ratios.
Cultural & historical context
White miso reflects the refined, restrained palate of Kyoto's court and temple cuisine, where subtlety and elegance were prized over the robust funk of rural styles.
