Tip

Reduce Added Salt When Using Bouillon

A standard bouillon cube provides 950-1300 mg of sodium per cup of broth — far above the 300-500 mg in typical homemade stock. Always taste before adding any additional salt to a dish made with bouillon. For rice or pasta cooked in bouillon broth, you may need no additional salt at all. Low-sodium cubes (350-500 mg/cup) are a practical compromise for people monitoring sodium intake.

Standard Cube-to-Broth Ratios

Different bouillon brands and forms produce different broth strengths from the same volume of water. Use this calculator to convert between cubes and finished broth volume.

Adjusting Strength: Light, Standard, Concentrated

The standard cube-to-water ratio (1 cube per cup) produces broth at the strength manufacturers intend — full-flavored but heavily salted. Adjust based on use:

For risotto specifically, use standard ratio: the rice absorbs the broth gradually over 20 minutes, and the proper ratio prevents the dish from becoming over-salted as the broth reduces.

Sodium Awareness and Reduction Strategies

The biggest challenge with bouillon is sodium content. A standard cube provides 50-75% of the daily recommended sodium intake (2300mg) in just one cup of broth. Strategies to reduce sodium without losing flavor:

Bouillon vs Broth vs Stock: Practical Differences

These three terms are often used interchangeably but have meaningful differences in cooking applications.

Stock is made by simmering bones (often roasted) for 4-12 hours, extracting collagen and minerals. Rich body, gels when cold, low sodium, deep flavor. Best for: braises, sauces, soups featuring the stock flavor.

Broth is made by simmering meat (and sometimes bones) for 1-3 hours, plus aromatics and salt. Lighter body, flavorful, moderately salted. Best for: most cooking applications, drinking, quick soups.

Bouillon is dehydrated broth concentrate with added salt, MSG, and flavor enhancers. Convenient, shelf-stable, high sodium. Best for: cooking applications where the broth flavor isn't featured (rice, beans, simmering pasta), camping, emergencies, busy weeknights.

For most home cooking, the practical hierarchy is: homemade stock > store-bought low-sodium broth > Better Than Bouillon > standard cubes. But all four work for cooking — the differences in flavor are subtle in finished dishes.

Storage and Shelf Life

Bouillon cubes: Sealed package: 2 years at room temperature. Once opened, transfer remaining cubes to airtight container; quality holds 18 months. Cubes are very moisture-sensitive — humid pantries can cause them to soften and clump.

Better Than Bouillon paste: Sealed jar: 2 years. After opening: refrigerate, lasts 18 months. Watch for mold or off odors.

Reconstituted broth (made from cubes/paste): Use within 7 days refrigerated, or freeze in ice cube trays for 3 months. Frozen broth cubes (each = 2 tablespoons) are convenient for adding small amounts to sauces.

Don't store bouillon cubes near strong-smelling foods (coffee, garlic, fish) — they absorb odors readily.
