(Glucono-delta-lactone)GDL, also known as gluconalactone.
Instructions
1. Pouring Method
Measure the GDL with a mini digital scale. Make sure you get the right amount. (Avoid using ¼ tsp as is not accurate)
In a large bowl (at least 1000 ml capacity), mix the GDL with 1 tbsp water and stir to dissolve.
Heat the soy milk to near boiling point. ( if you have not already done it)
Pour the soy milk from a height of about 30cm or, 1 foot, into the bowl with the GDL. As I poured it from less than 30cm, I am giving it a very quick stir instead.
Cover and set it aside for about 25 to 30 minutes.
The soy pudding is ready to serve.
You might want to remove the bubbles from the surface before serving or scooping it to a bowl to serve.
Top with the sugar syrup or with the savoury topping.
2. Pouring & Stirring Method
As before, dissolve 1.25g of GDL in 1 tbsp of water in a bowl.
Pour the hot soy milk and give it a quick stir ( 3 stirs).
Remove some of the bubbles if you can but I suggest you do it quick so as not to disturb the coagulation.
Set aside for 25 to 35 minutes.
2.0 Steaming Method
Here we use 500ml of cold soy milk
Dissolve 1.25g of GDL with 1 tbsp of water.
Gently pour in the soy milk and give it a gentle stir to avoid bubbles.
Cover the lid of the steamer with a piece of cloth to avoid steam dropping onto the pudding.
Steam this over medium heat for about 8 to 9 minutes.
You can also ladle this into smaller dishes or containers and steam.
Leave to cool a bit before serving.
Alternatively, wrap the bowl with cling film and steam.

Notes
Conclusion:Both methods are good. The pouring method is good if you work fast and try not to make too much bubbles. Texture wise it is ok and acceptable.It is easy as you do no have to steam which involves additional steps and extra washing up.The steaming method gives the best texture and very little bubbles. So, this is good presentation wise. But it involves more work. So, it is up to you which method you use.
