Mirin

Mirin is a type of rice wine and a common ingredient in Japanese cooking. It is similar to sake but with a lower alcohol content and higher sugar content. The sugar content is a complex carbohydrate that forms naturally during the fermentation process; no sugars are added. The alcohol content is further lowered when the liquid is heated. Three types of products are marketed as mirin. The first is hon mirin (literally: true mirin), which contains about 14% alcohol and is produced by a 40 to 60 day mashing (saccharification) process. The second is shio mirin (literally: salt mirin), which contains a minimum of 1.5% salt to prevent consumption in order to avoid alcohol tax.
