” The Chayei Adam 39:1 writes that the melacha of boneh (building) applies to food as well, and that attaching foods together to produce a desired picture or shape, is included in this prohibition.
from the OU… does that mean that one can close his/her eyes and make sloppy sushi on Shabbos?
Why is non-fresh sushi less tasty? I’ve never taste-tested the difference. And usually the non-fresh kind that I’ve purchased was inexpensive. The rice gets kind of hard.
But maybe storing fresh sushi for a day isn’t so bad. For someone who never eats sushi during the week and really enjoys it, maybe it’s a special Shabbos treat?
