It turns out tofu can be stored in a surprisingly simple way—yet very few people know about it.

Tofu is a familiar ingredient in many households. It is easy to cook, versatile, and offers numerous health benefits thanks to its high protein content and plant-based nutrients. However, one common problem many people face is how to store leftover tofu after buying it but not using it all at once. Most people habitually put unused tofu straight into the refrigerator, assuming this will keep it fresh longer. In reality, this method often causes tofu to turn sour, become crumbly, and spoil quickly—sometimes in just one day.

So what is the correct way to store tofu? Below are two simple yet highly effective methods shared by long-time tofu shop owners. When stored properly using these techniques, tofu can stay fresh, soft, and odor-free for up to 10 days without turning sour.

Method 1: Boil the Tofu Before Storing

How to do it:

• Rinse the tofu gently, then place it in a pot with enough cold water to fully submerge it.

• Bring the water to a boil and keep it boiling on high heat for about 2 minutes.

• Turn off the heat and let both the water and tofu cool naturally.

• Once completely cooled, remove the tofu, drain well, place it in a zip-top bag or airtight container, and store it in the refrigerator.

Why this works:

Boiling helps eliminate bacteria and enzymes that cause sourness and spoilage. At the same time, it helps the tofu maintain a smooth, firm texture. Storing it in a sealed container reduces contact with air and limits bacterial growth, significantly extending its freshness.

Method 2: Soak Tofu in Salt Water and Sichuan Peppercorns

This method uses the natural antibacterial properties of salt and Sichuan peppercorns, making it especially suitable for hot and humid climates.

How to do it:

• Prepare a bowl of boiled water that has cooled completely. Add one tablespoon of salt and about 10 Sichuan peppercorns, then stir well.

• Cut the tofu into serving-sized pieces and submerge them fully in the solution.

• Cover tightly and store in the refrigerator.

Salt and Sichuan peppercorns both have mild antibacterial effects that help slow down the growth of spoilage-causing bacteria. Tofu stored this way remains white, soft, and fresh, without becoming slimy or developing unpleasant odors.

Extra Tip: How to Fry Tofu Without Breaking or Sticking

If you have struggled with tofu falling apart or sticking to the pan when frying, try this simple trick:

• Heat the pan well, then rub a slice of fresh ginger around the surface to create a natural non-stick layer.

• Add cooking oil once the pan is moderately hot, then carefully place the tofu pieces in. Avoid flipping too early to prevent breaking.
  
  

• When both sides are golden and crispy, you can add seasoning or a light sauce to braise briefly, depending on your taste.

With these easy storage and cooking tips, tofu can become even more convenient and enjoyable in your daily meals. Proper storage not only reduces food waste but also ensures that every tofu dish you prepare remains delicious, fresh, and safe to eat.
