yes but the coarseness obviously varies from kosher vs table salt. and diamond crystal vs mortons. here's a good guide that i discovered:

1/4 c table salt = 1/2 cup Morton's kosher
1/2 cup Morton's kosher = 1 cup Diamond Crystal brand kosher

just looked over your recipe and it calls for a tsp of salt... for such a small quantity won't be so significant i don't think, more a personal preference.
