Cornstarch bagels

I leave you the recipe for cornstarch donuts like the ones our grandmothers made. These memories are the ones that one never forgets, and you?

Ingredients

• Corn starch 150 fallow deer
• Sifted powdered sugar 125 grams
• 1/4 teaspoon baking powder
• 1/4 ammonium carbonate (can be purchased at bakeries)
• Soft butter one teaspoon
• 2 yolks
• Milk if necessary a little

Preparation

Sift together the baking powder, cornstarch, and ammonium carbonate.

Beat in a bowl of butter together with the powdered sugar until a cream is left, add the yolks one at a time while continuing to beat.

Incorporate the sifted dry elements and join everything with your hands. It should be a hard but handy dough. If it shreds (it is very possible that it will happen) add cold milk little by little (one tablespoon at a time or droplets).

Take pieces of dough, make sausages as if you were to make gnocchi, cut the strips about 10 centimeters and join the ends forming the donuts and pressing the union well.

Lift them with the spatula and arrange them well separated on a greased plate with cornstarch. Once all the donuts have been assembled like this, go to sleep or do your daily tasks for 1 hour and 1/2, then turn the donuts with a spatula leaving them in the same place they occupied on the plate.
Cook them in a moderate oven with the oven door ajar so they don't crack, dry out without browning, and look like the donuts my grandmother used to eat. Remove the plate from the oven and let them cool and enjoy.
