Purple Yam Two-Tone Bread: A Slice of Filipino Sunshine

The first time I tasted ube bread, it was a serendipitous moment during a bustling food fair in Manila. The aroma alone, a sweet, earthy fragrance unlike anything I’d encountered, drew me in. The vibrant purple hue of the bread was mesmerizing, and the taste—a delicate balance of sweetness and subtle yam flavor—transported me. It felt like sunshine captured in a slice, a taste of the Philippines that I knew I had to recreate. The memory of that perfect loaf continues to inspire me, and I’m thrilled to share my take on this delightful treat.

Equipment Needed

• Measuring cups and spoons or kitchen scale
• 26cm loaf pan (approximately 10 inches)
• Wire rack

Instructions

1. Prepare the Tangzhong Starter: In a bowl, whisk together the water and the bread flour until the mixture is well blended and lump-free.
2. Cook the Tangzhong: Place the bowl over medium heat (or in a saucepan on the stovetop) and stir the mixture constantly. Cook until it reaches 65°C/149°F, which should take about 3-5 minutes. The mixture will thicken into a glue-like consistency. It’s crucial to maintain this temperature for proper gluten development.
3. Cool the Tangzhong: Remove from heat and cover loosely with plastic wrap to prevent it from drying out. Allow it to cool completely. Once cooled, the starter can be stored in the refrigerator.
4. Prepare the Ubi Dough: In a mixing bowl, combine all the ubi dough ingredients (except the butter).
5. Mix the Ubi Dough: Using a dough hook attachment (or mixing by hand), mix on slow speed for 1 minute. Then, increase the speed to medium and continue mixing until a dough begins to form.
6. Incorporate the Butter into the Ubi Dough: Gradually add the softened butter to the dough while mixing on medium speed. Continue mixing for approximately 5 minutes, or until the gluten is fully developed. The dough should be elastic, smooth, non-sticky, and pull away from the sides of the bowl. If the dough is too wet, add a touch of flour, one teaspoon at a time.
7. Prepare the Light Dough: Follow the same process as the ubi dough, combining all the light dough ingredients (except the butter) in a separate mixing bowl. Mix on slow speed for 1 minute, then increase to medium speed until a dough forms.
8. Incorporate the Butter into the Light Dough: Gradually add the softened butter to the light dough while mixing on medium speed. Continue mixing for approximately 5 minutes, or until the gluten is fully developed. The dough should be elastic, smooth, non-sticky, and pull away from the sides of the bowl. Adjust with a touch of flour or water as needed.
9. First Rise: Place each dough in separate, lightly greased plastic bags. Let the doughs rise in a warm area for about 45 minutes, or until they have doubled in bulk.
10. Punch Down: Once the doughs have doubled, gently punch them down to release the air.
11. Rest: Cover the doughs and allow them to rest on a lightly floured work surface for 10 minutes. This step helps relax the gluten, making the dough easier to roll out.
12. Shape the Bread: Roll out each dough to a rectangle, approximately 22x10cm.
13. Layer the Doughs: Place the purple ubi dough atop the light dough.
14. Roll and Place in Pan: Starting from the short side, tightly roll up the layered doughs. Place the rolled dough into a greased 26cm loaf pan.
15. Second Rise: Cover the loaf pan and let the dough rise until it has doubled in bulk again, which should take about 45 to 60 minutes.
16. Bake: Preheat your oven to 170°C/340°F. Bake the bread for 30-35 minutes, or until it is golden brown and cooked through. To check for doneness, insert a toothpick into the center of the bread; it should come out clean. If the top of the bread is browning too quickly, tent it with foil during the last 10-15 minutes of baking.
17. Cool: Remove the bread from the pan and let it cool completely on a wire rack before slicing and serving.

Expert Tips & Tricks

• Tangzhong Secret: Don’t skip the Tangzhong starter! It’s the key to incredibly soft and moist bread. Make sure to cook it to the correct temperature (149°F / 65°C). If you don’t have a thermometer, look for a thick, glue-like consistency.
• Ube Power: The quality of your ube powder matters. Look for vibrant purple ube powder for the best color and flavor. If you can find fresh ube, you can steam or boil it until tender, then mash it and incorporate it into the dough, adjusting the liquid accordingly.
• Kneading Know-How: Proper kneading is essential for developing the gluten. If you’re kneading by hand, it will take about 10-15 minutes to achieve the desired elasticity.
• Proofing Perfection: A warm, humid environment is ideal for proofing dough. You can create this by placing the dough in a slightly warmed oven (turned off!) with a bowl of hot water.
• Shiny Crust: For a glossy crust, brush the top of the loaf with an egg wash (1 egg beaten with 1 tablespoon of milk or water) before baking.
• Don’t Overbake: Overbaking will result in dry bread. Start checking for doneness around the 30-minute mark.

Variations & Substitutions

• Gluten-Free: Substitute the bread flour with a gluten-free bread flour blend. You may need to add a binding agent like xanthan gum.
• Dairy-Free: Use non-dairy milk and butter alternatives like almond milk and coconut oil.
• Sweetness Level: Adjust the amount of sugar to your preference. You can also add a touch of honey or maple syrup.
• Ube Extract: If you can’t find ube powder, you can use ube extract, but be mindful that it may contain artificial coloring. Add it gradually until you achieve the desired color and flavor.
• Other Root Vegetables: While ube is the star, you could experiment with other root vegetables like sweet potato or taro, adjusting the recipe as needed.

FAQs (Frequently Asked Questions)

Q: What is Tangzhong and why is it important?
A: Tangzhong is a cooked flour and water mixture that adds moisture and softness to bread. The pre-gelatinized starch allows the dough to absorb more liquid, resulting in a tender crumb and longer shelf life.

Q: Can I make the Tangzhong ahead of time?
A: Yes, you can prepare the Tangzhong and store it in the refrigerator for up to 3 days. Be sure to bring it to room temperature before using it in the dough.

Q: My dough is too sticky. What should I do?
A: Add a tablespoon of flour at a time until the dough becomes manageable. Be careful not to add too much, or the bread will be dry.

Q: How do I know when the bread is done?
A: The bread is done when it is golden brown and a toothpick inserted into the center comes out clean. The internal temperature should reach around 200-210°F (93-99°C).

Q: Can I freeze this bread?
A: Yes, this bread freezes well. Wrap it tightly in plastic wrap and then in a freezer bag. It can be stored in the freezer for up to 2 months.
