The first step will be to create the choux dough. To do so take a pot and add in the 25 g Butter and the 250 ml Milk and the Salt, keep on medium heat and allow it to come to a boil. Take the pot with the liquid short away from the heat and add in the flour, keeping on stirring at the same time.
Take the pot back to law heat and keep on stirring! Don't waste time at this point, stay focused becaue its important that you follow this step!
While you keep on stirring the dough will form a ball and at the bottom, you will notice a layer of sticking flour. That is a sign that you did all correctly well!
Take the dough out and allow it too cool for some time, once it is ready to add the egg yolk to the dough, working the yolk with your hands gradually into the dough. When you do that make sure the dough is really cooled down or you ll have bits forming and the dough won't bind anymore how it is supposed to.
Form it into a big long sausage as shown.
Cut 12 slices out of the sausage and take it into your hand with a pat dried strawberry at the center.
Cover the strawberry with the dough and close it well or the chance that it will open while boiling will be higher.
It is important that it is well closed! Roll it a bit to form it into a smooth ball and keep aside. Do that will all slices and strawberries.
While you were forming the dumplings you kept a big pot with water to boil. Once it is boiling well add in the dumplings carefully and keep the flame on slow and stir everynow and then, so that they dont stick at the bottom. Cook them for 7-10 minutes.
While the dumplings are cooking, take out a pan and fry the Breadcrumbs with the Butter (ratio should be 1:1, to your liking). The breadcrumbs should have a gold brown hue when finnished fryed.
The Dumplings are ready when they swim on top. Take them carefully out, strain a bit the water and directly roll them into the breadcrumbs butter mixture. Coat them well.
Before you serve them sprinkle some sugar on top to your liking. enjoy!
Notes
I used relatively small Strawberries ( I had no choice), try to get bigger ones for this recipe.
