But you ca n't beat them for freshness , and however they look , they certainly taste good . I ' m still playing around with plating them , but here you can see an asparagus roll , a cucumber - avacado roll , and a California roll made with shrimp in place of the typical faux crab . I always wondered why they used faux crab ( which consists primarily of processed halibut scraps molded into a sort of fishy McNugget ) , but my guess now is that the reasons are primarily aesthetic . While the faux crab has that bright red coloring to it , the shirmp is basically just rice colored , and does n't much stand out when you slice up the maki .
