Ingredients
Scaled for 2 servings
- 2 cups whole milk (must be full fat, preferably not ultra-pasteurized)
- 2 tbsp sugar
- 2 large pieces of old, fibrous ginger (needs to yield 2 tbsp of strong juice)
Equipment
- Fine grater
- Thermometer (mandatory)
Instructions
- 1
Grate Ginger
Peel the ginger. Grate it finely using a ceramic ginger grater or microplane.
- 2
Extract Juice
Gather the grated ginger in your hand and squeeze it as hard as you can over a small bowl. You need exactly 1 tablespoon of pure ginger juice per serving.
- 3
Prepare Bowls
Place 1 tablespoon of the freshly squeezed ginger juice into the bottom of two small serving bowls.
- 4
Heat Milk
In a saucepan, heat the milk and sugar over medium heat, stirring until the sugar dissolves.
- 5
Check Temperature
Use a thermometer. Heat the milk until it reaches exactly 165°F (75°C). Turn off the heat. The temperature is critical for the reaction.
- 6
Stir Ginger
The white starch in the ginger juice will have settled to the bottom of the bowls. Stir it vigorously to re-suspend it right before the next step.
- 7
The Pour
Hold the saucepan high above the bowl and pour the hot milk rapidly into the ginger juice. The force of the pour mixes it.
- 8
DO NOT TOUCH
Do not stir it! Do not move the bowls. Leave them completely undisturbed on the counter.
- 9
The Magic
Wait 3-5 minutes. The enzymes in the ginger juice will curdle the milk proteins into a delicate custard.
- 10
The Spoon Test
To test if it worked, gently place a ceramic soup spoon on top of the curd. If the spoon sits on the surface without sinking, the pudding has set.
- 11
Serve
Serve immediately while warm. It will be spicy, sweet, and incredibly soft.
- 12
Eat
Scoop it gently; stirring will break the fragile curds and turn it back into liquid.
Cooking Tips
- You MUST use old ginger (with rough, dry skin). Young ginger does not contain enough of the specific enzyme (zingibain) needed to curdle the milk.
- The milk temperature must be exactly 70°C-75°C (160°F-165°F) when it hits the ginger. Too hot and the enzyme is destroyed; too cold and the reaction won't happen.
Variations
- Papaya Milk Curd: A similar enzyme reaction can be achieved using the juice of a completely unripe, green papaya.
