The title of this recipe is perhaps misleading because this is neither a recipe for “authentic” kimbap and it is certainly not sushi. Technically sushi is sushi because of the vinegared rice and the rice in kimpab uses sesame oil and salt for seasoning. I usually combine all seasonings (vinegar, sugar, salt, sesame oil) so call these what you want. Regardless, these are super delicious and very impressive, but really affordable and easy to make.
You can literally fill these rolls with anything. I tend to use veggie fillings because it’s quick, cheap and keeps well for work lunches. Feel free to get creative though. Kimbap can have bulgogi, eggs, fishcakes and more. I’m sure there are also a million possibilities that aren’t traditionally in kimbap or sushi like smoked salmon or tempeh. You do you, and don’t let anyone tell you this isn’t “real” kimbap.
