What can I use instead of sea salt (fine) for cake?
Table Salt at 1:1 is the closest match — Interchangeable in baking. Table salt usually carries iodine and anti-caking agents; flavor difference is negligible in dough. If that is unavailable, Kosher Salt (Diamond Crystal) (Use 2x the volume (1 tsp fine sea salt = 2 tsp Diamond Crystal)).
