Ingredients for ขนมปุยฝ้ายสีรุ้ง

• 50 g (1/3 cup) tapioca starch or cornstarch
• 1 tsp baking powder, sifted
• 1/4 tsp salt
• 150 g (3/4 cup) granulated sugar, divided
• 4 large eggs, separated (yolks and whites)
• 150 ml (2/3 cup) coconut milk, room temperature
• 80 ml (1/3 cup) water, room temperature
• 60 ml (1/4 cup) neutral vegetable oil (canola or sunflower)
• 1/2 tsp cream of tartar (or 1 tsp lemon juice) for stabilizing egg whites
• Natural or gel food coloring for rainbow layers:
  • blue: butterfly pea extract or blue gel
  • green: pandan extract or green gel
  • pink/red: beetroot juice or red gel
  • yellow/orange: carrot juice, turmeric, or orange gel
  • purple: ube/taro powder or purple gel
• Optional: small paper or silicone cupcake cups (makes about 12 small cakes)

Instructions to Make ขนมปุยฝ้ายสีรุ้ง

1. Prepare the steamer: Fill a large pot or steamer with water and bring to a gentle boil. Line the steamer lid with a clean kitchen towel to catch condensation, or use a lid cover if available. Prepare 12 small cupcake cups and place them on a heatproof tray that fits inside your steamer.
2. Mix dry ingredients: In a bowl, sift together the cake flour, tapioca starch, baking powder, and salt. Set aside.
3. Combine yolks and wet ingredients: In a separate large bowl, whisk the egg yolks with half the sugar (75 g) until slightly pale. Add coconut milk, water, and vegetable oil, whisking until combined. Gradually fold in the dry flour mixture until a smooth batter forms—do not overmix.
4. Whip egg whites: In a clean, grease-free bowl, add egg whites and cream of tartar. Whisk on medium speed until foamy. Gradually add the remaining sugar (75 g) in three additions while whipping to glossy, stiff peaks. The meringue should hold shape and not slide.
5. Combine batter and meringue: Fold one-third of the meringue into the yolk batter to lighten it. Gently fold in the remaining meringue in two additions using a spatula with slow lifting motions—keep as much air as possible for an airy texture.
6. Divide and color the batter: Divide the finished batter evenly into 5 small bowls (or as many colors as you like). Add a few drops of natural extract or gel color into each bowl and stir gently until the color is even. Use small amounts—gel colors are more concentrated.
7. Layer the colors: Spoon about 1–2 tablespoons of the first color into each cupcake cup. Continue layering each color gently on top of the previous layer until cups are about 3/4 full. For a swirled look, use a skewer to make gentle figure-eight motions without deflating the batter.
8. Steam the cakes: Place the tray with cups into the preheated steamer. Steam over medium-high heat for 12–15 minutes for small cups (adjust to 18–22 minutes for larger molds). Do not open the lid frequently. After steaming, turn off the heat and let the cakes sit covered for 2 minutes before removing the lid to avoid sudden temperature changes.
9. Check doneness and cool: Insert a toothpick into the center—if it comes out clean, the cakes are done. Remove cups from the steamer and let cool for a few minutes before unmolding. Serve warm or at room temperature.

Cooking Tips for ขนมปุยฝ้ายสีรุ้ง

Practical tips to help beginners succeed when making ขนมปุยฝ้ายสีรุ้ง:

• Room temperature eggs and liquids whip better—take eggs out of the fridge 20–30 minutes before starting.
• Use a clean, dry bowl for egg whites; any grease will prevent proper whipping.
• Fold gently to keep the batter airy. Overmixing will deflate the meringue and make denser cakes.
• If using natural colorings (like vegetable juices), strain liquids to remove pulp so they blend smoothly into the batter.
• Cover the steamer lid with a towel to prevent water droplets from falling on the cakes and leaving marks.
• Adjust steaming time based on mold size: smaller cups need less time; larger pans need more. Always test with a toothpick.
• For even layers, spoon small amounts of each color and rotate the tray slightly between layers.
