Quick Answer
Which should I use?
For most sourdough baking, standard iodized table salt (jodsalz) and natural salts (sea/rock salt) both work. Choose iodized salt for consistency and availability; choose natural salt for subtle mineral complexity and texture. Both affect fermentation mainly through ionic strength; differences are minor when used at typical usage (1.8–2.2% of flour weight) [1][2].

Comparison Table
| Property | Option A | Option B | Significance |
|---|---|---|---|
| Typical iodine addition | Contains added iodide/iodate | No added iodine (trace natural only) | Iodized salt supplies dietary iodine; tiny effect on dough chemistry |
| Anti-caking agents | Often contains anti-caking additives | Usually pure crystals or flakes | Anti-caking agents are inert in dough at baking doses |
| Crystal size | Fine, uniform | Coarse flakes or crystals | Coarse salt dissolves slower; can affect surface saltiness and crust texture |
| Mineral complexity | Minimal (mostly NaCl) | Contains minor minerals (Mg, Ca, trace elements) | Natural salt can add subtle flavor notes |
| Effect on fermentation | Limits yeast activity proportionally to NaCl concentration | Same primary effect; minor differences from trace minerals negligible | Salt concentration is the main variable — type matters less than percent |
| Flavor impact | Clean, consistent saltiness | Mineral, briny, sometimes sweeter or more complex | Use natural salt where mineral notes are desired |
| Availability & price | Very available, cheap | Wider price range; specialty options cost more |
When to Use Which?
Predictable dissolution and consistent salting; good for fine crumb and tolerance to slight under-mixing [1].
Adds surface crunch and mineral complexity; use finely ground for even distribution or sprinkle flakes on shaped loaves before baking [1][2].
Salt slows yeast and enzyme activity; maintain recommended 1.8–2.2% to avoid over- or under-fermentation [2].
Finer salt disperses more evenly so lower amounts taste saltier; monitor fermentation closely as reduced salt speeds activity [1].
Iodized salt ensures iodine; natural salts may be low in iodine — important if table salt is main iodine source [2].
Can I Mix Both?
Can You Mix Salts?
Yes. Many bakers blend fine iodized salt for consistent bulk salting and finish with flaky natural salt on the crust for texture and flavor contrast. Use a [dough scraper/bench knife](https://amzn.to/3LR1f5E) or gentle folding to distribute salt evenly during mixing.
Converting Recipes
A → B
Flour: No change
Water: No change
→ Swap 1:1; adjust if switching between very large crystals and fine salt — coarser salt may require slight increase (by volume) but weigh salt to avoid mistakes
B → A
Flour: No change
Water: No change
→ If using flaky finishing salt instead of dissolved salt, reduce bulk salt so total sodium remains similar
💡 Always weigh salt on a [digital kitchen scale](https://amzn.to/4pUMVHi). If converting by volume, remember coarse sea salt has lower density than fine table salt: 1 tsp fine table salt ≈ 6 g; 1 tsp coarse sea salt ≈ 4–5 g. When trying a new salt, bake one loaf keeping salt% constant and adjust by taste next time [1][2].
