Concentrated Stock Dilution Calculator

Calculate how to dilute concentrated stock, bouillon, or base to full-strength broth.

Ratios vary by brand and concentration level - always check the specific product's label for its recommended dilution ratio, since some concentrated bases are significantly stronger than others.

About the Stock Dilution Calculator

The Concentrated Stock Dilution Calculator figures out how much bouillon cube, paste, or liquid concentrate is needed to produce a target amount of full-strength broth. It's aimed at cooks working from a recipe that calls for broth or stock but who are starting from a concentrated product instead of a ready-made liquid, whether that's a shelf-stable cube, a jarred paste base, or a bottled liquid concentrate.

How It Works

You enter how many cups of full-strength broth the recipe requires and select the concentrate type: bouillon cube, concentrated paste or base, or liquid concentrate. For cubes, the calculator returns a whole number of cubes needed. For paste or liquid concentrate, it returns a teaspoon amount based on a fixed ratio per cup of broth.

bouillon cubes needed = ceiling(cups of broth needed); paste needed in teaspoons = cups of broth x 1; liquid concentrate needed in teaspoons = cups of broth x 2

Formula & Methodology

Each concentrate type is handled with its own conversion. A standard bouillon cube is assumed to dissolve into about 1 cup, or 8oz, of broth, so the cube count is simply the broth volume rounded up to the next whole cube, since a partial cube isn't a practical unit. Concentrated paste or base is assumed to use 1 teaspoon per cup of broth, while liquid concentrate is assumed to run stronger in volume terms and use 2 teaspoons per cup, so both are calculated by multiplying the broth volume by their respective per-cup teaspoon rate.

Examples

Paste Base for a Pot of Soup

A recipe calling for 4 cups of broth, made from concentrated paste at 1 tsp per cup, needs 4 x 1 = 4 teaspoons of paste.

Bouillon Cubes for a Smaller Batch

A recipe calling for 2.5 cups of broth, made from bouillon cubes at roughly 1 cup per cube, needs ceiling(2.5) = 3 cubes.

Advantages

  • Handles three distinct concentrate formats, cube, paste, and liquid, with the conversion logic appropriate to each, rather than a single blanket ratio.
  • Converts a recipe's broth requirement directly into a shopping or measuring quantity for whichever concentrate is on hand.
  • Rounds cube counts up automatically, avoiding the awkward question of how to measure a fractional cube.

Common Mistakes

  • Assuming all concentrate types use the same dilution ratio, when paste, liquid concentrate, and cubes are calculated differently here because they differ in strength and format.
  • Not checking the actual product label, since real-world dilution ratios vary by brand and can be stronger or weaker than the general reference rates used here.
  • Adding a recipe's full salt amount on top of bouillon-based broth, without accounting for how salty many bouillon products already are.

Edge Cases to Watch For

  • The cube count is always rounded up to a whole number, since cubes can't practically be measured in fractions.
  • Dilution ratios vary meaningfully by brand and concentration strength, so the fixed rates used here are general reference points rather than universal standards, and checking the specific product label is recommended.
  • Bouillon-based broth is often significantly saltier than a homemade or ready-made stock, so recipes may need less added salt elsewhere when built from bouillon.

Common Use Cases

  • Home cooks substituting bouillon or concentrated base for stock called for in a recipe.
  • Meal planners keeping shelf-stable concentrate on hand instead of cartons of liquid broth or stock.
  • Anyone scaling a soup or sauce recipe up or down and needing to recalculate how much concentrate to use for the new broth volume.

Frequently asked questions

Is concentrated stock/base nutritionally or flavor-wise the same as fully simmered stock?

Not exactly - commercial concentrated bases are often built more around salt, flavor extracts, and sometimes MSG for a strong, consistent flavor punch, while homemade stock develops its body and richness from actual collagen and gelatin extracted from bones over hours of simmering - concentrates are a convenient, shelf-stable shortcut, but many cooks still prefer real stock for dishes where that gelatin-derived body matters, like a proper pan sauce or risotto.

Conclusion

Concentrated stock products let a cook stock a pantry with a shelf-stable substitute for broth, but only if diluted at roughly the right ratio for the recipe. This calculator turns a target broth volume into a practical measuring amount, with the product label always the final word on brand-specific strength.
