Is it permitted to make a sushi roll,using precooked rice,on shabbos. Are there any authorities that permit making filter coffee,with the manual pour method on shabbos.
It is permitted to make a sushi roll on Shabbos, if all this involves is rolling up one food with another. If raw vegetables are used, the rice should not be very hot, out of concern for “cooking” the vegetables with the heat of the rice.
It is not permitted to manually pour coffee through a filter on Shabbos, due to the prohibition of borer.
