Salt in baking is a volume trap: every crystal shape weighs something different per teaspoon, so swapping table salt for kosher without adjusting can leave bread under-seasoned or, worse, slow the yeast and overpower a cookie. Table salt also strengthens gluten and tempers yeast fermentation, so the substitute has to deliver the same milligrams of sodium — not the same scoop.
Use Use 2x volume (1 tsp table = 2 tsp Diamond Crystal) for the closest replacement in most recipes.
Fine sea salt is the cleanest 1:1 swap for table salt — the crystal size and density are nearly identical, so a teaspoon delivers the same seasoning and the same gluten-tightening effect, with a trace mineral note instead of iodine.
View adjustment notes →Salt at 1.8-2.2% of flour weight is the standard, and that math assumes you're weighing. If you must measure by volume and only have Diamond Crystal kosher, use 2 tsp for every 1 tsp table salt called for — otherwise the dough over-ferments and the crumb goes gummy.
Table salt dissolves into the hot sugar syrup invisibly; fine sea salt does too at 1:1. Reserve flaky Maldon for finishing only — stirring it into the caramel base wastes the crunch and concentrates pockets of salinity that read harsh once cool.
Recipes like chocolate chip or shortbread often call for 3/4 tsp table salt. Fine sea salt swaps in 1:1 with no recipe change, but if you only have Morton kosher, use 1 tsp; with Diamond Crystal, push to 1 1/2 tsp to hit the same flavour.
