Double Skin Milk Pudding

Traditionally made with high-fat buffalo milk for the richest texture, modern home versions use full-cream cow's milk (or a mix with cream) and achieve excellent results.

Ingredients (makes 3–4 small servings)

• Full-fat whole milk (whole milk ≥3.5% fat; the higher the better) — 450–500 ml (about 2 cups)
• Egg whites — 2 large (about 60–80 g total; roughly 1 egg white per 200–250 ml milk)
• Sugar — 30–45 g (2–3 tbsp, adjust to taste; traditionally light sweetness)
• Optional for richer version:
  • 30–60 ml heavy cream or light cream (to mimic buffalo milk fat content)
  • A few drops of vanilla extract (modern addition, not traditional)
• Optional toppings (serve chilled or warm):
  • Fresh mango cubes, strawberries, or other fruit
  • Sweet red beans (蜜红豆)
  • A light dusting of osmanthus syrup or honey

Equipment Needed

• Small heatproof bowls or ramekins (ceramic or glass, 150–250 ml each)
• Steamer setup (or a wok with steaming rack + lid)
• Fine mesh strainer
• Whisk or fork
• Thermometer (helpful but not mandatory)

Step-by-Step Instructions

1. Prepare the steamer
   Fill a wok or steamer pot with water and bring it to a boil over medium-high heat. Reduce to maintain a steady simmer once boiling. (The water level should be below the steaming rack.)
2. Heat the milk to form the first skin (key step for authentic double skin)
   Pour the milk (and cream if using) into a small saucepan.
   Heat over medium heat, stirring occasionally, until it reaches a gentle boil or small bubbles appear around the edges (about 82–85°C / 180–185°F). Do not let it boil vigorously.
   As soon as small bubbles form, turn off the heat immediately.
   Let the milk sit undisturbed for 5–10 minutes. A thin milk skin (奶皮) will form on the surface as it cools slightly.
3. Gently separate and reserve the first skin (optional but recommended for pronounced double skin)
   Using a small knife or spoon, carefully loosen the edges of the milk skin.
   Very gently lift or slide the skin aside (or onto the side of the pot).
   Slowly pour the warm milk underneath into a mixing bowl, leaving about 1–2 tablespoons of milk in the pot to help the skin stay attached if you want to transfer it later.
   (Some simplified modern recipes skip separating the skin and just mix everything — it still works but has only one obvious skin layer.)
4. Mix the custard base
   Add the sugar to the warm milk in the bowl. Stir until completely dissolved.
   In a separate clean bowl, lightly beat the egg whites with a fork or whisk until frothy but not stiff (do not whip into meringue — just break them up).
   Slowly pour the beaten egg whites into the sweetened milk while stirring gently and continuously.
   Mix until fully incorporated and smooth (no big egg white clumps).
   Optional: Add 2–3 drops vanilla extract here.
5. Strain for ultra-smooth texture
   Pass the mixture through a fine mesh strainer into a clean bowl or directly into the serving bowls. This removes any tiny egg white bits or bubbles, giving the signature velvety finish.
6. Add the first skin back (if you separated it)
   Gently place the reserved milk skin back on top of the mixture in each bowl (it may tear a little — that’s fine; it will still look beautiful after steaming).
   If you didn’t separate it, skip this — the second skin will form during steaming.
7. Steam the pudding
   Cover each bowl tightly with foil or heatproof plastic wrap (to prevent water droplets from falling on the surface).
   Place the bowls on the steaming rack.
   Steam over medium-low heat for 10–15 minutes (small bowls ~10–12 min; larger ones ~13–15 min).
   The pudding is done when it jiggles like soft tofu/very soft custard but is set (a toothpick inserted should come out mostly clean with a little wet custard).
   Do not over-steam — it turns grainy or rubbery.
8. Cool and form the second skin
   Remove from steamer and let sit at room temperature 10–15 minutes.
   A second thin wrinkled milk skin will form on top as it cools.
   Then refrigerate for at least 1–2 hours for the classic chilled version (or enjoy warm).
9. Serve
   Serve chilled (most popular) or warm.
   Eat directly from the bowl with a spoon — the contrast between the thin, chewy milk skins and the ultra-smooth, milky pudding underneath is divine.
   Add fresh fruit or red beans on top if desired.

Quick Tips for Success & Common Fixes

• Use high-fat milk → The higher the fat, the thicker & silkier the skins and texture.
• Don’t over-beat egg whites → Just mix until uniform; too much air = bubbles in pudding.
• Medium-low steam → High heat causes cracking or holes.
• If no skin forms → Milk wasn’t hot enough initially, or too much stirring disturbed the surface.
• If texture is grainy → Over-steamed or egg whites not fully incorporated.
• Simplified version (no skin separation) → Heat milk → dissolve sugar → mix in egg whites → strain → steam directly. Still delicious, though traditionally one skin is less prominent.
