Applied Salt vs. Equilibrated Salt

Entry 001

I began working with two pieces side by side.

Same cut. Same size. Same starting weight.

One was treated with applied salt. The other was weighed and salted to equilibrium.

For this round, I used two salts I have worked with at their source.

Nothing else was adjusted.

Materials

• Whole muscle cut, trimmed to consistent geometry

• Salinas de Maras salt (Peru), fine, dense crystal structure

• Kep sea salt (Cambodia), larger flake, more open structure

• Scale for total mass calculation

• Controlled refrigeration environment

No additional variables introduced beyond salt origin and application method.

Method

For the applied piece, Salinas de Maras salt was distributed across the surface until coverage felt complete. No percentage was calculated.

For the equilibrated piece, Kep sea salt was weighed as a fixed percentage of total mass and applied evenly across all surfaces.

Both were placed on racks under the same conditions.

No further intervention.

Early Observations

The Maras salt began drawing moisture quickly. The surface became wet in patches, with some areas dissolving almost immediately while others held briefly before breaking down.

The Kep salt remained visible longer. The flakes sat at the surface before gradually dissolving, and moisture developed more slowly and more evenly.

The difference appeared first in how the surface responded.

24 Hours

The applied piece began to show variation across the surface. Areas where the Maras salt dissolved quickly started to tighten, while other areas remained softer.

The equilibrated piece continued to move more evenly. The Kep salt had mostly dissolved, but without creating the same immediate saturation at the surface.

The surface remained more consistent across the piece.

72 Hours

The applied piece showed clear inconsistency. Some areas had begun to dry and firm, while others lagged behind.

The equilibrated piece continued to align more uniformly. There was less visible contrast between surface and interior.

The difference in salt structure and composition appeared to influence how quickly and where moisture moved.

Handling

When cut, the applied piece showed a more pronounced gradient. The outer layer had begun to set, while the interior remained softer.

The equilibrated piece transitioned more gradually from surface to center.

Salt presence was perceptible in both, but expressed differently.

What Is Not Yet Known

• How calcium and magnesium present in the Maras salt are influencing moisture movement and surface formation

• Final internal salt distribution in each piece

• Water activity at each stage

• Whether crystal structure or mineral composition is the dominant factor

No measurements have been taken to confirm these conditions.

Next Iteration

• Repeat using the same salt for both methods to isolate application effect

• Reverse the salts between methods

• Track weight loss over time

• Introduce water activity measurements without using them to guide decisions

Notes

I have worked with both of these salts at their source. They do not behave the same even before they touch the product.

That difference becomes more visible once they are applied.

The Maras salt tends to collapse into solution quickly, creating localized saturation at the surface. The Kep salt holds its structure longer and distributes moisture interaction more gradually.

This behavior may be influenced by the presence of calcium and magnesium in the Maras salt, though this has not been measured.

Both systems are active.

They are not behaving the same.
