Luxury Uni Sea Urchin Flavor Potato Chips from Yamayoshi

“Uni (うに, 雲丹)”, or sea urchin is known as a luxurious sushi topping loved by gourmets, and in Japan, the yellow roe is even used as a flavoring for snacks.

Among such treats, “Unisen (うにせん)“, or Uni Senbei has been around for quite some time and is most widely enjoyed today, but until a while ago I hadn’t seen Uni or sea urchin flavor potato chips. 

However, yesterday I accidentally found that Yamayoshi Seika, a confectionery maker known for Wasa-Beef Potato Chips, had already created that.

Actually, I came across the “Uni Mamire (うにまみれ: sea urchin-plastered)” potato chips at a 7 Eleven store yesterday and bought one for sampling.

According to some online sources, the product was first introduced in May of 2019 and renewed recently.

Sea Urchin Potato Chips

Since the roe of sea urchin is an expensive ingredient, the Uni potato chip is priced at 140 yen (about 1.3 USD) per bag (48 grams) and costs a little bit more compared to average potato chips.

I tried out these sea urchin potato chips just now and found them quite unique in taste and flavor; distinctive umami taste kind of reminiscent of the sea comes first, followed by the sweetness characteristic of Uni.

Yes, the Uni potato chip was pretty good, and if you can somehow get it, for its novelty factor, I recommend you giving it a try at least once.
