Sweet Potato Scones

Steam or bake the sweet potato in the oven, then mash it and let it cool. Warm up the milk, add the sugar and yeast. Thoroughly mix the egg yolk with the mashed sweet potato and butter. Add the activated yeast and start adding the flour.

Don't worry, you will get a very soft dough, do not add extra flour!

Cover the kneaded dough and let it rise for about 1 hour.
