In KALDI's seasoning aisle, the bottled-jar series from the Japanese-food brand "Moheji" is so popular it's almost always running low on stock. And among them, the undisputed king — boasting an overwhelming repeat-purchase rate — is the "Iburigakko Tartar Sauce."
Tartar sauce typically consists of mayonnaise mixed with onion and pickles, but this product replaces the pickles with a generous helping of "iburigakko" — the famous smoked pickled daikon radish from Akita Prefecture. The moment you open the lid, a smoky, rich aroma of smoked goodness rises up. With the tartness of mayonnaise dialed back and the sweetness and umami of iburigakko pushed to the forefront, this sauce is something entirely different from the "tangy tartar sauce" we all know.

Scoop it up with a spoon and you'll see that finely chopped iburigakko has been kneaded in by the absurd spoonful. Pile it generously on fried shrimp, fried oysters, or chicken nanban, take a bite, and right after the crispy crunch of the batter, the satisfying "crackle and crunch" of iburigakko comes chasing after.
Within the rich, deep flavor of mayonnaise, the smoky aroma and the sweetness of daikon burst forth, and what should be greasy fried food gets sucked into your stomach at frightening speed. Rather than "a sauce for eating fried food with," it's more like "fried food you fry just so you can eat this sauce" — its presence is so powerful that the roles end up completely reversed.

The truly terrifying thing about this tartar sauce is its "abnormal level of versatility" beyond fried food. Use it as a dipping sauce for steamed or raw vegetables like broccoli, asparagus, cucumber, or carrots, and even kids who hate vegetables will gobble them up at a surprising pace.
What's more, slather it generously on a slice of bread, top with cheese, and toss it in the toaster, and you'll have an exquisite "iburigakko toast" where the smoky aroma really shines. Stir a tablespoon into potato salad and it instantly class-changes into a "grown-up smoky potato salad" worthy of an upscale department-store deli. Just having a single jar in the fridge will explosively expand the variety of your daily menu.
| Just Put It on a Cracker. The Ultimate "Instant Snack"

On nights when even cooking feels like too much trouble, simply spreading it on a cracker or baguette makes it a perfectly respectable dish on its own. It pairs beautifully with wine, beer, and even sake — the makings of "the ultimate instant snack" that will keep you drinking endlessly.
It has the same addictive quality as the classic "iburigakko × cream cheese" combination, but with the mellow smoothness of mayonnaise added in, the result is a milder flavor with much broader appeal. As a hors d'oeuvre for unexpected guests, it's an absolute can't-miss staple.

The price is around 462 yen (tax included) for a single 160g jar. That's a bit pricier than your standard mayonnaise or tartar sauce, but considering how lavishly the domestic iburigakko is used, and the magical power it has to turn any ingredient into a "feast," it's by no means expensive.
"KALDI's Iburigakko Tartar Sauce" is a flawless masterpiece seasoning that will spark a smoky revolution at the grown-up dinner table. If you haven't tried it yet, the next time you spot it at KALDI, definitely toss one into your basket. You'll surely find yourself running back for a second jar.
