First, we prepare the yeast starter in the usual way
In a bowl, mix 3–4 tablespoons of flour with lukewarm milk and water.
Add the sugar and yeast and wait 20–30 minutes for a nice starter to form.
Add the remaining ingredients to the bowl. Knead into a soft, supple dough and let it rise again for 30–40 minutes.
On a floured work surface, shape into the form of a dumpling – an elongated loaf. Let it rise for at least another 20 minutes.
We steam it in the classic way on a steamer (we put water in the bottom of the pot, place a greased steamer – or place baking paper on it so the dumpling doesn't stick.
Place the dumpling and steam for 20 minutes. Do not open the pot at any time during this.
After 20 minutes, take the dumpling out onto a wooden board. Prick it with a toothpick, put about 1 tsp of oil on your hand and rub the dumpling so it doesn't dry out. The dumpling will remain wonderfully fluffy even if you prick it with a toothpick.
Its preparation is simple, and it has never failed me.
