Sudachi: Japanese Baby Lime Cookie Recipe

Soft and chewy, sweet yet tart—is your mouth watering yet?

What’s a すだち (sudachi)? Think of it as a tiny, tart lime native to Tokushima Prefecture in Japan. Every now and then, I stay up way too late experimenting with seasonal fruits—testing my patience, my oven, and definitely blowing past my daily calorie limit. But hey, it’s all in the name of delicious research. Today, I’m sharing one of my favorite recent successes: soft and chewy sudachi cookies made with these bright little Japanese citrus gems.

Sudachi Season

Sudachi might be small, but it’s thoughtfully mighty. This little green citrus fruit is super zesty and a bit sharper than lime, perfect for giving dishes a fresh kick. It’s in season from late August through October, and in Japan, it pops up everywhere: sliced over grilled fish, squeezed into soba dipping sauce, mixed into ponzu or even stirred into cocktails.

Beyond its punchy flavor, sudachi’s packed with vitamin C and antioxidants. While it’s more common in savory dishes, I decided to do something different and bake with it, and that’s how my sudachi cookie recipe was born. Think buttery, lightly citrusy and just the right kind of tart. But be warned—sudachi are tougher than you’d imagine! Getting juice out of them (good luck) is a mission. I ended up going with pre-packaged, 100% sudachi juice (not from concentrate), and honestly, it worked like a charm.

Soft & Chewy Sudachi Cookie Recipe

I’m “this” (air-pinch 1 cm) close to saying these are my new, forever-and-ever favorite cookies. They’re not overwhelmingly, pucker-up tart but the citrus is definitely there. You can smell it, you can taste it. If you want more of a punch, though, I would add another two teaspoons of sudachi juice and just enough flour to avoid making the dough super rubbery.

Ingredients

• 225 g (8 oz) cream cheese (softened)
• 300 g (1 ½ cups) sugar
• 1 egg
• 113 g (½ cup) salted butter (softened)
• 280 grams (2 ¼ cups) all-purpose flour
• 2 teaspoons (10 ml) sudachi juice
• 1 teaspoon (5 ml) vanilla
• 65 g (½ cup) powdered sugar
• 2 teaspoons baking powder
• Another 100g (just under 1 cup) of powdered sugar

Instructions

1. Preheat your oven to 180C (or 350F).
2. Mix together the cream cheese, butter, and sugar.
3. Add in the egg, vanilla, and sudachi juice.
4. Sift the flour, powdered sugar, and baking powder together (this will prevent any lumps in the dough).
5. Take the dough and roll it into about the size of a golf ball.
6. The dough is sticky at this point but now roll it into powdered sugar. Once you roll the dough—don’t be shy—it should help the dough become smooth and easy to manipulate.
7. Place on a baking sheet lined with parchment paper.
8. Bake for 9 minutes or so. If they haven’t changed color, add a minute or two. After they’re done baking, keep them in the turned-off oven for another 5 minutes. This will collapse the cookie.

I tried them fresh out of the oven, and the next morning (purely for science, mind you). Personally, I liked them better the next morning. The sudachi is much more settled in and noticeable.

May sudachi become a new staple in your cooking and baking—it’s now my newfound secret weapon. You’ll be surprised by how much flavor is packed into each of those little babies. Enjoy!
