With so many specialty salt options available today, it can get confusing distinguishing between them. Sea salt and kosher salt are two common types used in cooking and finishing dishes. While they share some traits, there are important differences that impact taste, texture, and how they should be used.
Salt Origins and Production
Sea salt is harvested from evaporating sea water, so it contains trace minerals that give it some unique flavor and color. Kosher salt gets its name because it follows traditional Jewish koshering methods, though it can be used by anyone.
Grain Size
The biggest difference between sea and kosher salt is the crystal size. Sea salt granules range from fine to chunky in texture. Kosher salt grains are much larger and coarser, almost like little crystals. The large grains make kosher salt easier to pinch and spread evenly.
Flavor Profile
Sea salt has a more complex, nuanced flavor thanks to mineral content. The taste can vary slightly depending on its origin. Kosher salt has a pure, clean salty taste without appreciable minerals or aftertaste. The large crystals also deliver a satisfying crunch.
Culinary Uses
The delicate flavors of sea salt shine when used as a finishing salt. It balances sweetness and enhances natural flavors. Kosher salt is ideal for koshering meat, lining rim glasses, and for other applications where its texture provides control.
Health Profile
Sea salt and kosher salt have comparable sodium levels when used in equal amounts. Sea salt contains small amounts of minerals like potassium, iron, and zinc not found in purified kosher salt. But the quantities are minimal.
Cost Differences
Kosher salt is quite inexpensive, costing approximately $1 per pound. Sea salts run $5-15 per pound depending on quality. Specialty artisanal sea salts can cost even more.
Iodine Content
Standard table salt has added iodine, an important nutrient. Neither sea salt nor kosher salt contains iodine. Those monitoring iodine intake may prefer iodized table salt for general use to avoid deficiency.
In Summary
While both sea and kosher salt add salty flavor, sea salt’s specialty flavor profile and coarser kosher salt texture set them apart in terms of best culinary uses. Kosher salt seasons meat and rims glasses well. Finishing dishes with sea salt adds a touch of elegance.
