If you make your own maki sushi at home, but are looking for ways to change it up, here are some goodies chowhounds love tucked into their rolls.
Crunchy stuff: takuan (pickled daikon); crunchy, sweet, tart, and salty, all at the same time. Thin strips of green apple. Cucumber with umeboshi (pickled plum) paste.
Cooked stuff: tempura shrimp, oysters, or squid.
Flavoring stuff: bits of dill or mint; spicy mayo; other flavored mayos.
Really unexpected but delicious stuff: tangerine or orange segments.
