For centuries, salt curing has been a fundamental method for preserving food, allowing civilizations to store meat, fish, and even vegetables for extended periods. Before refrigeration, salt was a vital tool in food preservation, enabling people to keep food edible for months or even years. Today, salt curing remains a valued technique, not just for preservation but also for enhancing flavor and texture. In this blog, we will explore the history, science, and modern applications of saltalong with a guide to trying it at home.
A Brief History of Salt Curing
Salt curing dates back thousands of years, with evidence suggesting that early civilizations, including the Egyptians, Chinese, and Romans, used salt to preserve food. The method became essential for sailors, traders, and military forces, as it allowed them to carry food over long journeys without spoilage.
Over time, different cultures developed their own variations of salt curing. The Italians perfected prosciutto, the Spanish created jamón, and the Japanese mastered curing fish for sushi. Even today, salt curing remains a significant part of traditional cuisine worldwide.
How Does Salt Curing Work?
Salt curing works by drawing moisture out of food, creating an environment where bacteria and microorganisms cannot thrive. This dehydration process helps prevent spoilage and extends the shelf life of food. Additionally, salt alters the texture and enhances the flavor of food by breaking down proteins and fats.
Salt curing generally falls into two main categories:
- Dry Curing – Applying salt directly to food, allowing it to absorb the salt and expel moisture.
- Wet Curing (Brining) – Submerging food in a saltwater solution, which helps preserve and tenderize it.

Salt is most commonly used for meats and fish, but it can also be applied to other foods. Here are some of the most popular salt-cured foods:
1. Meat
