How to Store and Freeze Sunomono
Fridge: Store leftover sunomono in an airtight container in the refrigerator for up to 3 days. The flavors will continue to develop, making it even tastier!

Reheating: Since sunomono is served cold, there’s no need to reheat. Simply pull it from the fridge and enjoy—it’s perfect for a quick and refreshing snack!
Preparation Tips: If you plan to make sunomono ahead of time, keep the dressing separate until you’re ready to serve. This prevents the cucumbers from getting too soft.
Expert Tips for Making Sunomono
Slice Thinly: Make sure to cut the Japanese cucumber into thin, even slices to enhance texture and flavor.
Don’t Rush Salt: Allow the cucumber to sit with sea salt for the full 10 minutes; this helps to draw out moisture and keep your salad crispy.

Can I freeze Sunomono?
No, I don’t recommend freezing sunomono. Freezing will make the cucumbers mushy when thawed, significantly altering the texture you’ve worked so hard to perfect. It’s best to enjoy this salad fresh. If you want to prepare it ahead of time, keep the dressing separate until you’re ready to serve.
What if my Sunomono is too salty?
If you find your sunomono is on the salty side, you can balance it out by adding a bit more sugar to the dressing. Mix the dressing ingredients (rice wine vinegar, sugar, soy sauce, sesame seeds) and taste as you go. Aim for that delightful balance of sweet and salty! If it’s still too salty, try adding some extra fresh cucumber slices to dilute the saltiness.
Is Sunomono suitable for my gluten-free diet?
Definitely! To make sunomono gluten-free, simply replace the soy sauce with a gluten-free alternative, such as tamari. This way, you can still enjoy this delightful Japanese cucumber salad without any worries. Always double-check your dressing ingredients to ensure they’re gluten-free!
Can I add other ingredients to customize my Sunomono?
The more the merrier! You can absolutely customize your sunomono with additional ingredients. Consider adding thinly sliced carrots, radishes, or even a hint of sesame oil for added flavor. If you enjoy seafood, sliced shrimp or octopus can also elevate this dish to a new level!
