The Broth vs. Stock Difference: A Salinity Primer
The salt level in broth depends heavily on whether it is prepared from scratch or purchased from a grocery store. Understanding the difference between broth and stock is also key. Stock is typically made by simmering bones with vegetables and herbs, but usually without salt, to create a versatile base for other dishes. Broth, on the other hand, is made with meat and seasonings and is intended to be flavorful enough to drink on its own, which often means it is pre-seasoned. This fundamental distinction means that broth is more often designed to be salty from the start, while stock is intentionally kept bland to avoid over-seasoning a final dish.
Why Store-Bought Broth Tastes So Salty
Commercial broths are often heavily salted to ensure a consistent, palatable flavor profile directly from the carton, appealing to a broad range of consumers. This heavy salting enhances the umami flavor and helps mask variations in the quality or quantity of other ingredients. For many recipes, particularly those that require a reduction, this high sodium content can quickly become problematic, leading to an oversalted final product. In fact, some regular store-bought broths contain as much as 890 mg of sodium per cup, which is nearly half of the recommended daily intake. This is why chefs and home cooks alike often prefer low-sodium options or homemade versions to better control the seasoning.
How to Control Salt in Homemade Broth
Creating homemade broth allows for complete control over the sodium content, which is often much lower than store-bought varieties. A key tip from professional cooks is to avoid adding salt at the beginning of the simmering process. As broth cooks, the liquid reduces and the flavors concentrate. Adding salt early on will result in an intensely salty broth once the liquid has evaporated. Instead, add salt to taste at the very end of the cooking process, or even better, wait to season the final dish you are preparing with the broth. This method ensures a perfectly balanced flavor every time.
The Salt Factor and Broth Reduction
One of the most common reasons for an oversalted broth, especially homemade, is the reduction process. As the broth simmers, water evaporates, leaving behind a more concentrated and intensely flavored liquid. Since salt does not evaporate, its concentration increases significantly. This is why it's crucial to taste the broth throughout the cooking process and add seasoning in layers, rather than all at once. For sauces and gravies, a low-sodium or unsalted broth is often the best starting point to prevent over-seasoning when the liquid is reduced.
Comparison of Broth and Stock Characteristics
| Feature | Homemade Broth | Store-Bought Broth | Homemade Stock | Store-Bought Stock |
|---|---|---|---|---|
| Sodium Content | Low to Moderate (User-controlled) | High to Very High (Pre-seasoned) | Very Low (Unseasoned Base) | Low to Moderate (Usually less than broth) |
| Best Use | Drinking, light soups, quick bases | Soups, stews, dishes where flavor consistency is key | Base for sauces, gravies, stews | Base for cooking, often lower sodium than broth |
| Flavor Profile | Clean, fresh, balanced flavor | Often robust but sometimes artificial or one-dimensional | Mellow, gelatinous, unseasoned | Varied, but typically cleaner than pre-seasoned broth |
| Key Ingredients | Meat, vegetables, herbs, water | Water, salt, flavorings, yeast extract, caramel color | Bones, vegetables, herbs, water | Water, stock base, flavor enhancers, salt |
Quick Fixes for an Oversalted Broth
If you find yourself with an overly salty broth, all is not lost. Several simple culinary techniques can help rescue your dish.
- Dilute with water or unsalted liquid: The most direct method is to add more liquid, such as water or an unsalted broth, to decrease the overall salt concentration.
- Add acidity: A splash of lemon juice or vinegar can cut through the saltiness and balance the flavor profile.
- Introduce fat: Dairy products like cream, yogurt, or even unsalted butter can coat the palate, reducing the perception of saltiness.
- Bulk up with starches: Adding starchy vegetables like potatoes, grains, or rice can absorb some of the excess salt from the liquid.
- Rinse and repeat: For some canned or heavily brined ingredients, a quick rinse under water before adding them to the broth can reduce excess sodium.
Conclusion
While broth is not inherently meant to be salty, its salt level depends on whether it is homemade or store-bought, and its intended culinary purpose. Commercial broths are heavily salted for flavor and consistency, while homemade versions give the cook control over the sodium content. By understanding how salt concentrations change during cooking and using techniques like diluting, adding acid, or bulking up with starches, you can always ensure a perfectly balanced flavor. Seasoning gradually and tasting throughout the cooking process is the most reliable way to prevent an oversalted meal. By mastering these principles, you can take control of your broth and create delicious, balanced dishes every time.

Frequently Asked Questions
What is the ideal salt level for broth?
There is no single ideal salt level, as it depends on the broth's use. For a sipping broth, a moderate salt level is appropriate. For a cooking base, it is best to keep it unsalted or very lightly salted to allow for seasoning the final dish.
How can I make my homemade broth less salty?
The best way is to dilute it with unsalted liquid, such as water or a fresh, salt-free broth. Adding a peeled, raw potato or starchy grains like rice can also absorb some excess salt.
Why is my homemade broth so salty, even though I didn't add much salt?
Your broth may have become too salty due to reduction. As the liquid evaporates during simmering, the salt concentration becomes more intense. To avoid this, season cautiously and wait until the end of the cooking process to add salt to taste.
Do bouillon cubes make broth salty?
Yes, bouillon cubes and powdered bases are highly concentrated and typically contain very high levels of sodium, making any broth made from them quite salty. It is crucial to check the serving size and sodium content on the packaging.
Is stock less salty than broth?
Generally, yes. Stock is traditionally made without salt and used as a base, giving the cook control over seasoning in the final recipe. Store-bought stock also tends to have less sodium than store-bought broth.
What can I use besides salt to add flavor to my broth?
To enhance flavor without adding more salt, consider adding herbs like parsley or thyme, spices, a squeeze of lemon juice or vinegar, or aromatics such as garlic and onions.
Can I use store-bought broth and still control the saltiness?
Yes, choose low-sodium or unsalted store-bought broth options. This gives you the flexibility to add your own seasonings and salt to taste, rather than starting with a high-sodium base.
