Fresh homemade tofu is surprisingly simple to make using homemade soy milk and a coagulant. Once the soy milk is heated and combined with a coagulant such as calcium sulfate (gypsum) or nigari (magnesium chloride), the proteins naturally separate into curds and whey. The curds are then pressed into a firm block of tofu that's ready for stir-fries, soups, salads, grilling, and countless other recipes.
Making tofu from scratch gives you complete control over the texture, from soft and silky to extra firm.
Important: This recipe contains soy. Soy is one of the nine major food allergens recognized in the United States and is not suitable for individuals with a soy allergy.
Homemade Tofu Recipe
Prep Time: 15 minutes
Cook Time: 30 minutes
Press Time: 20–60 minutes
Yield: Approximately 1 pound of tofu
Ingredients
- 8 cups fresh, unsweetened homemade soy milk
- 2 teaspoons calcium sulfate (food-grade gypsum) or
- 1½ teaspoons nigari (magnesium chloride)
- ½ cup warm water
Equipment
- Large saucepan
- Thermometer (optional but helpful)
- Wooden spoon
- Fine-mesh strainer
- Cheesecloth
- Tofu mold (or small colander)
- Heavy object for pressing
Step-by-Step Instructions
Step 1: Prepare the Soy Milk
Begin with freshly made, unsweetened soy milk.
If refrigerated, gently reheat it over medium heat until it reaches approximately 170–180°F (77–82°C).
Avoid letting it boil vigorously.

Step 2: Prepare the Coagulant
Dissolve your calcium sulfate or nigari in warm water.
Stir until completely dissolved.
Step 3: Add the Coagulant
Remove the soy milk from the heat.
Slowly stir in about half of the dissolved coagulant using gentle, sweeping motions.
Wait one minute.
If the curds haven't fully formed, slowly stir in the remaining coagulant.
The soy milk should separate into:
- Soft white curds
- Pale yellow liquid (whey)
Allow the mixture to rest for approximately 15 minutes.
Step 4: Prepare the Mold
Line a tofu mold or small colander with damp cheesecloth.
Place it over a bowl or sink to catch excess liquid.
Step 5: Transfer the Curds
Using a slotted spoon or ladle, gently transfer the curds into the prepared mold.
Fold the cheesecloth over the top.
Step 6: Press the Tofu
Place the mold lid (or another flat surface) on top.
Add weight.
Press according to your preferred texture:
| Texture | Press Time |
|---|---|
| Silken | No pressing |
| Soft | 15–20 minutes |
| Medium | 25–35 minutes |
| Firm | 45–60 minutes |
| Extra Firm | 60–90 minutes |
More pressing removes additional moisture, creating firmer tofu.
Step 7: Cool
Remove the tofu from the mold.
Place it in cold water for several minutes to help it firm up before slicing.
How to Store Homemade Tofu
Store tofu submerged in clean, cold water in an airtight container in the refrigerator.
Change the water daily.
For the best quality, enjoy within 3 to 5 days.
Discard if it develops an off odor, slime, mold, or other signs of spoilage.
Tips for Better Homemade Tofu
- Use fresh soy milk.
- Do not use sweetened or flavored soy milk.
- Heat gently—avoid boiling vigorously.
- Stir slowly when adding the coagulant.
- Allow enough resting time for the curds to fully develop.
- Adjust pressing time to achieve your preferred texture.
Which Coagulant Should You Use?
Calcium Sulfate (Gypsum)
- Traditional choice
- Mild flavor
- Produces slightly firmer tofu
- Adds a small amount of calcium
Nigari (Magnesium Chloride)
- Traditional Japanese coagulant
- Creates a smoother, silkier texture
- Popular for artisan tofu
Both produce excellent tofu.

Frequently Asked Questions
Can I use store-bought soy milk?
Yes, but it should be plain, unsweetened, and contain as few added ingredients as possible. Homemade soy milk generally produces more consistent results.
Why didn't my soy milk separate?
Possible causes include:
- Soy milk wasn't hot enough.
- Too little coagulant was used.
- The soy milk contained stabilizers or additives.
- The mixture wasn't allowed to rest long enough.
Why is my tofu crumbly?
Too much coagulant or pressing too firmly can produce a dry, crumbly texture.
Can I freeze homemade tofu?
Yes.
Freezing changes the texture, making tofu firmer and more porous. Many people enjoy frozen tofu because it absorbs marinades exceptionally well.
Is homemade tofu healthier than store-bought?
Homemade tofu lets you control the ingredients and contains no added preservatives. Nutritional values vary depending on the soy milk concentration and coagulant used.
