Can the amount of salt in the recipe be right?
It's been a while since I made sushi but 2 tablespoons does sound a little on the ridiculous side.

Various other recipes use similar amounts (to each other):


AllRecipes: 1 tsp salt (for 1/2 cup vinegar and 4 tbsp sugar)
Alton Brown: 1 tbsp kosher salt (for 2 tbsp vinegar and 2 tbsp sugar)
SushiRecipes: 1 tsp salt (for 1/2 cup vinegar and 1/2 cup sugar)
Epicurious: 1/2 tsp salt (for 2 tbsp vinegar and 1 tbsp sugar)


In fact, although sushi rice recipes tend to vary significantly with respect to the proportions of rice, vinegar, and sugar, they are all remarkably consistent on the amount of salt.  The Alton Brown recipe calls for a tablespoon, but 1 tbsp of kosher salt is in fact equivalent to 1-2 tsp of table or sea salt.  Even on the Epicurious recipe, the 1/2 tsp is only for 1 cup of rice - you'd double it to the same 1 tsp for the standard 2 cups.

I assume that the recipe you're looking at must have meant 2 tsp and not tbsp, but I think even that is too much; I would stick to the 1 tsp used in almost every sushi rice recipe I've ever seen.
