Concept:
Miso is a traditional Japanese seasoning produced by fermenting a high-protein substrate.
• It uses a mold starter called "Koji" (Aspergillus oryzae).
• It is a thick paste used for sauces and soups.
Step 1: Identifying the core ingredient.
The primary ingredient in Miso is mashed cooked soybeans.
Sometimes rice or barley is added to the mixture.
Step 2: Understanding the fermentation.
The Koji mold breaks down the soybean proteins into amino acids.
Salt is added to inhibit the growth of spoilage bacteria during the long aging process.
Step 3: Evaluating other options.
Fermented cabbage is called Sauerkraut.
Fermented black gram is used in products like Idli and Dosa.
