How to Make Clear Broth Without Off-Odors
Start by Understanding What Causes Off-Odors
Meaty off-odors come from proteins in blood residue cooking and releasing a smell, while anchovy and seafood off-odors come from oils in the innards and heads spreading as they boil. Vegetables can give off a grassy smell if simmered too long. In short, every ingredient has parts that should be discarded and a proper timing for when it should be added.

How to Prep Each Ingredient
- Beef and beef bones: Soak in cold water for at least 30 minutes to draw out blood residue, then bring to a boil once and discard the first water (blanching).
- Anchovies: Remove the heads and black innards, then toast in a dry pan for 1 to 2 minutes to drive off fishy smells.
- Chicken: Cut away the yellow fat deposits under the skin and remove the tail.
- Dried herring: Since it has a deeper flavor than anchovies, remove only the head before using.
Making Clear Anchovy-Kombu Broth
Here is the most commonly used basic broth as an example. The key is to remove the kombu before the water boils and steep the anchovies only over low heat. If the broth boils vigorously, the kombu mucilage and anchovy oil are released, making the broth cloudy.
Cleaner and Deeper Flavor
- For a clearer broth: Skim off the gray foam that rises during boiling 3 to 4 times with a spoon.
- For a richer broth: Add 2 dried shiitake mushrooms for extra umami (guanylic acid).
- For meat broth: Add 5 whole peppercorns and 2 garlic cloves to sharply reduce gamey odors.
- When you are in a hurry: Put anchovies and kombu directly into cold water and leave them in the refrigerator overnight for a clear cold-steeped broth without boiling.
Let leftover broth cool slightly, then store it in the refrigerator for 2 to 3 days or in the freezer for up to 1 month. Freezing it in an ice cube tray makes it easy to add one cube at a time to ramen or stir-fried dishes. However, reheating is recommended only once; repeated boiling and cooling makes broth spoil more easily, so handle it with care.
