Today (02/12/2021) is the Lunar New Year. 2021 is the year of Ox, Happy “Niu” Year! “Niu” is the pronunciation of ox in mandarin, in Chinese, croissants are also called Niu Jiao Bao, Ox Horn Bread because the shape of croissants. To celebrate the Lunar New Year, I adopted croissants to a more Asian flavor with my favorite Cantonese steam bun – lava bun with salted egg yolk 流沙包, and taro fillings.
Flowy, running salted egg yolk fillings recipe still needs to improve, but overall flavor is very surprising and delicious!
QUICK TAKEAWAYS
- fold each croissant dough on both ends of the fillings, after proofing to dough will perfectly wrap around and seal fillings inside
- need to improve the salted egg yolk fillings recipe to make it flowy
RECIPE
Portions: 7-8 croissants
- 262g All Purpose Flour (should be 250g, was adjusted)
- 70g water (RT)
- 70g whole milk (RT)
- 27.5-28g sugar
- 20g butter (RT)
- 5.5g yeast
- 6g salt
- 145g lamination butter (31% of dough weight, 465g)
Salted egg yolk fillings (8g/portion):
- 2 salted egg yolk (~25g)
- 12g milk powder
- 15g sugar
- 18g butter
Taro (12g/portion):
- 80g taro
- 15g milk
- 25g sugar
- 10g butter
- pinch of salt
DAY 1: ~1hr
Step 1: bring out yeast and butter from fridge, warming out to room temperature (butter becomes soft and yeast activates)
Step 2: mix 5.5g yeast with 70g water, 4g sugar, set for 10-15mins (foam appearing = yeast activating).
Step 3: mix 1g ube extract, 250g AP flour, 70g milk, 20g soft butter, 24g sugar and 6g salt, yeast water. Form dough.
Step 4: rest dough for 20mins, then knead till smooth.
Step 5: wrap dough tightly with plastic wrap try to prevent fermentation before lamination), first chill in freezer for 1 hour (according to this recipe, attached below) then move to fridge and store overnight.
DAY 2: ~1.5-2 hours
Dough weight: 465g
Butter weight (31%) = 465 * 31% = 145g
Step 1: slice 145g European butter (>80% fat), place in a 15cm x 15cm square-shape parchment paper. Put back in fridge if too soft.
Step 2: bring out the croissant dough, roll out large enough so that it can completely seal the butter sheet like an envelop. If they are not the same texture, put both back in fridge to harden them.
Step 3: wrap butter sheet with croissant dough. Then roll it into a rectangle shape long enough to fold as blanket. If there are air bubbles in croissant dough, poke it with a knife.
Step 4: Fold into blanket shape, rest in fridge for 30mins.
Step 5: repeat step 3 and 4 twice, so there are three rolling and folding in total. Rest in fridge overnight.
- decrease to 3-fold for every fold now (3-3-3), instead of 3-4-4; last time using this butter the lamination was not good and butter almost all melted.
- no skin broke on the 2nd fold, some skin broke on the 3rd fold, especially on the edge

Fillings:
Step 1: Salted egg yolk fillings — shred 2 egg yolks (~26g), mix well with 18g soft butter (at room temperature), 12g milk powder, 15g sugar, then divide into 8 portions; store in fridge.
- 67g/8 = 8g per portion
Step 2: Taro fillings — steam 80g taro slices till soften (around 20mins), then mix with 10g butter, 25g sugar, 15g milk.
Step 3: stir taro fillings on pan over medium heat till moist evaporates, and not sticking on spatula or spoon
Step 4: let it cool down, divide into 8 portions than put in fridge
- 100g/8 = 12g per portion
- not wrap around salted egg yolk fillings right away because taro fillings are warm and might melt butter in salted egg yolk
Step 5: wrap taro around salted egg yolk fillings, shape as longer cuboid (as shown below), store in fridge overnight
- too flat or round as a ball with make croissant shaping very weird
- both taro and salted egg yolk are pretty malleable; if too hard, first shape them as balls, wait for a few minutes and further reshape into cuboids
DAY 3: ~3 hours
Step 1: slightly press down croissant dough to get rid of air inside. Slightly rolling out to a small rectangle. Remove fillings from freezer to fridge.
Step 2: roll out carefully for the final croissant sheet for shaping (base of 40cm, height of 25cm, thickness of 4-5mm). Make sure each croissant triangle has base of 10cm, height of 25cm, thickness of 4-5mm.
- put back in fridge when roll for too long
Step 3: put croissant dough sheet back in fridge for 15-30mins. All the rolling before might warm up croissant dough especially in summer, making croissant dough sticky and “skin” break.
Step 4: slice croissant dough sheet into triangles, cut a 1-2cm opening at triangle base’s midpoint. place filling at the base and roll up tightly. Stretch out the base, roll and press down slightly to make sure no opening between the filling and the dough like the right figure.

Step 5: brush with egg, proof in closed oven with hot water beneath (26-28C) for 2 hours or when size doubles.
- first time see lamination in such contrasting colors, and the butter is a bit uneven
Step 6: brush with egg again before baking. Bake at 400F for 10mins, 375F for 10-12mins.
Step 7: remove from oven, brush with diluted honey in water and cool for 15mins
READY TO ENJOY!!
