Easy and Smooth Sweet Potato Dessert - steamed sweet potatoes

Method

• Prepare the food processor.
• Cook quickly while the steamed sweet potatoes are still warm.
• Add all the ingredients into the food processor, and mix.
• If it's hard to mix, add 1 teaspoon of milk at a time to make the mixture smooth.
• When it becomes smooth, transfer into an icing bag, and squeeze it out.
• The consistency should be the same as soft koshi-an (smooth sweet red bean paste).
• It's easy to squeeze out the mixture while it's still warm.
• Brush with the egg yolk or milk (excluded from the ingredients) on the surfaces of the sweet potato dessert to make them lustrous if you would like.
• Bake in the oven for 10 minutes at 200C, and they're done.
• When baked, the surfaces are lightly browned.
