Of the asian breads that have risen to fame, Shokupan must be a sure shoo-in for one of the most popular breads. Although it looks practically identical to regular white breads in shape, this Japanese milk bread stands apart by having an incredibly soft and fluffy texture that lasts for days. This is largely thanks to its popular derivative ingredient, Yudane, the gelatinized starch mixture that also adds a natural sweetness to the bread. When this Yudane is paired with the right composition of ingredients, we get a perfectly made loaf. That is exactly what we're going to do in this video, and naturally, we're using science to guide our way. From the proper making and use of Yudane, to the optimum amounts of milk, sugar, salt, and butter, we'll look into everything we need to know for the perfect loaf. Watch the video for more!

Loaf Pan
External Dimension 21x11x12 cm3
Internal Dimension 19.5x10x10.8 cm3

Ingredients:
Tangzhong
Bread Flour 60 g
Boiling Water 120 g

Final Dough
Bread Flour 240 g
Sugar (Sucrose) 18 g
Milk 50 g
Butter 15 g
Whole Egg 50 g
Salt 5 g
Instant Yeast (1/2 tsp) 1.8 g

Note on hydration calculation:
Water in Tangzhong 120 g
Water in Milk 0.87x50 = 43.5 g
Water in Whole Egg 0.74x 50 = 37 g
Water in butter 0.18x15 = 2.7 g
Total Liquid = 203.2 g
Total Flour = 300 g
Hydration = 100%*203.2/300 = 67.7%
