Pour NutriSoy Fresh Soya Milk (No Sugar Added) into a pot and place it over low to medium heat. Stir continuously to prevent it from sticking to the bottom.
Heat the soy milk until it reaches a gentle simmer, around 80–84°C. Use a thermometer for accuracy.
Turn off the heat and take the pot off the stovetop.
Pour in half of the lemon juice and stir gently for 1–2 minutes.
If the soy milk begins to curdle and thicken, stop stirring to avoid breaking the curds.
Pour in the rest of the lemon juice and gently stir in a figure-eight motion to distribute evenly.
Cover the pot and let it rest undisturbed for 15 minutes to allow full curd formation.
Carefully strain the curds using a cheesecloth. Transfer the curds into a tofu mold or a container lined with cheesecloth. Press down with a weight to form a firm block. Pressing tofu requires 6hrs-12hrs.
Once pressed, remove the tofu from the mold. Rinse gently with cold water, then refrigerate or use immediately.
