An amazing Japanese dashi-style concentrate, with umami up the proverbial wazoo. Use in any recipe that calls for dashi, diluted with four times or more as much water (for broths or soups) or at or near full strength as a dipping sauce for noodles or whatever. When using as a substitute for dashi, keep in mind that this is already highly seasoned, so you might want cut back on any additional soy or salt called for in the recipe.
Recipe cribbed from Jeffrey Alford & Naomi Duguid's Seductions of Rice.
Makes approximately 4.5 cups.
2 6x4" pieces of Kombu, lightly rinsed
12 Dried Shiitakes
1-1/2c small dried whole sardines or anchovies (ask your Korean or Japanese grocer)
3 c soy sauce
1 c mirin
1 c sake
1. Combine all ingredients in a bowl, cover, and let stand overnight at room temperature.
2. Transfer to a heavy pot and bring to a boil over high heat.
3. Let boil for 1 min, then turn to low and let simmer for 3 min.
4. Strain, setting the solids aside for another use (see below) if desired.
5. Rinse a quart glass jar with very hot water. Cool the concentrate and then refrigerate. It will keep for up to 5 months.
To use: dilute up to 4:1 with water. Bring to a boil, boil briefly, then lower heat and simmer for a few minutes before serving.

The leftover solids may be used to make a quick broth for immediate use:
1. Soak kombu for 30m in 2 c water.
2. Add solids, bring to a boil.
3. Remove kombu, boil 10 min, strain.
Use within 24h, at full strength.
