This recipe for refreshing Soft Tofu and Cucumber Cold Soup combines soft, silky tofu and crisp cucumbers with a spicy and tangy broth, perfect for stimulating your appetite on a hot day.

📝 Editor's Notes

This Soft Tofu and Cucumber Cold Soup, easily prepared in about 15 minutes, is a delightful dish that brings back lost appetites during hot summer days, combining tender soft tofu with crisp cucumbers.

The spicy and tangy broth, complemented by the savory tofu, offers a refreshing yet satisfying meal in a single bowl.

It's especially perfect when you crave a cool soup or a light, healthy meal.

🛒 Ingredient Tips

When choosing cucumbers, it's important to pick fresh ones: look for those with vibrant color, no blemishes on the surface, and an un-withered stem.

Cucumbers that feel firm and heavy when touched usually have a higher water content and are crispier.

For soft tofu (연두부), always check the expiration date, and for packaged products, a fresh one will feel full and won't slosh around when shaken.

For cheongyang chili peppers (청양고추) and red chili peppers (홍고추), choose ones with bright colors and fresh stems for the best quality.

🔄 Substitution Guide

You can use silken tofu (순두부) instead of soft tofu (연두부).

However, silken tofu has a slightly firmer texture than soft tofu, so it's best to scoop it into larger chunks with a spoon.

If you don't have cucumber, you can use other crunchy vegetables like very thinly julienned daikon radish or lightly blanched bean sprouts.

Instead of tuna extract, you can use anchovy sauce (멸치액젓) for a deeper umami flavor, but adjust the amount as it can have a stronger seafood aroma.

For sweetness, honey or oligosaccharide can be used instead of allulose or sugar.

👨‍🍳 Cooking Points

There are two key points for this Soft Tofu and Cucumber Cold Soup.

First, when julienning the cucumber, use a mandoline or grater to slice it as thinly as possible.

This allows the seasoning to penetrate well and creates a good textural harmony with the soft tofu.

Second, it's crucial to add the soft tofu just before serving.

If added too early, the tofu can release moisture, diluting the soup's flavor and losing its shape.

Don't forget to add plenty of cold water and ice cubes to enjoy it refreshingly.

Marinating the cucumber with the seasoning first can also develop a deeper flavor.

👨‍🍳 Directions

1

Thinly slice 1 cheongyang chili pepper (청양고추) and 1 red chili pepper (홍고추).

2

Cut off the bitter ends of 1 cucumber, then julienne it finely using a mandoline or grater.

3

In a bowl, combine the julienned cucumber with 0.5 tbsp gochugaru (고춧가루), 1 tsp salt, 1 tbsp allulose or sugar, 2 tbsp vinegar, 0.5 to 1 tbsp tuna extract (참치액), 0.5 tbsp sesame seeds, and the sliced cheongyang and red chili peppers. Mix well.

4

Add 1¼ cups of water and ice cubes to the seasoned cucumber mixture, then mix thoroughly.

5

Carefully cut a small corner from the back of the 1 package (150g / 5.3 oz) of soft tofu (연두부) to release air. Gently slide out the tofu to prevent it from breaking apart, then cut it into bite-sized pieces.

6

Add the cut soft tofu just before serving. Your Soft Tofu and Cucumber Cold Soup is now ready.

💡 Tips

Add the soft tofu just before serving to prevent it from releasing too much moisture into the soup.

Add ice cubes for a more refreshing experience.

📦 Storage & Reuse

Before adding the soft tofu, you can store the cold soup base in the refrigerator for 2-3 days, keeping it fresh.

Store it in an airtight container and add fresh soft tofu just before serving.

Be careful not to store the soup with the soft tofu already added, as the tofu may become mushy and cloud the broth.

Leftover cucumber can be wrapped in plastic wrap and stored in the vegetable drawer of your refrigerator to maintain freshness.

Individually packaged products are hygienic and easy to store, so keep that in mind.
Q. What are the key tips for making 4 Super Easy No-Cook Recipes for Summer?
First, it is most important to thoroughly wash all ingredients before cooking. Especially for cucumbers and chili peppers, rinse them multiple times under running water to remove any residual pesticides. Second, it's best to season by adding the dressing gradually and tasting as you go, rather than adding too much from the start. Salt and vinegar, in particular, vary greatly in taste preference, so adjusting them to your liking is the key to success. Third, for soft ingredients like `yeondubu (연두부)` or `sundubu (순두부)`, add them at the final stage of cooking or mix gently to prevent them from breaking apart.

Q. How should I store leftover 4 Super Easy No-Cook Recipes for Summer?

The Cucumber, Crab Stick, and Tofu Sauce Salad and Soft Tofu and Vegetable Salad are best enjoyed immediately after mixing with the sauce. For leftovers, store the ingredients and sauce separately, then mix just before serving to maintain freshness.

However, note that `sundubu (순두부)` has a higher water content than `yeondubu (연두부)`, which may slightly cloud the cold soup if added. If you have an allergy or dislike cucumber, you can use other crisp cucumber varieties or slightly blanched Korean zucchini (`aaehobak (애호박)`). While the cool and refreshing taste of cucumber might be slightly different, it's a good way to increase vegetable intake. Instead of crab sticks, you can use shredded boiled chicken breast or canned crab meat to boost protein. The taste might vary slightly, but you'll still enjoy a savory and clean flavor that highlights the ingredients.
