Botan ebi, a prized type of deep-sea shrimp from Hokkaido, is loved for its plump texture and rich, concentrated flavor. Its delicate sweetness is followed by a deep umami that lingers pleasantly on the palate.
Botan ebi are widely distributed in the seas around Hokkaido, generally living at depths of approximately 100 to 400 meters. They are unusual in that they undergo a sex change as they mature, beginning life as males before developing into females.
Their reproductive organs initially develop as male structures. As these gradually degenerate and disappear, the female reproductive structures mature. This life cycle is known as protandrous hermaphroditism.
The first bite of fresh botan ebi reveals a distinctive firm, springy texture. Its natural sweetness quickly spreads across the palate, followed by a rich, almost creamy umami that remains pleasantly on the tongue.
Because of these qualities, botan ebi is particularly popular raw as sashimi or sushi. Its natural sweetness and fresh texture are especially easy to appreciate when served without heavy seasoning.
Although botan ebi is often enjoyed raw, it can also be prepared in other ways. Tempura brings out its sweetness while adding a crisp coating, while lightly grilling it with salt creates a deeper, more savory flavor.
The head should not be discarded. The rich shrimp miso inside the head is considered a delicacy in its own right. Lightly grilling the head brings out its intense flavor and makes the most of the entire shrimp.
March and April
Although botan ebi are landed from spring through autumn, supplies become limited during winter. Early spring, particularly around March, is traditionally considered the peak season when their flavor is at its best.
