Mix the flour, semolina, yeast, cornstarch and sugar in one bowl.
In a large bowl or large measuring cup, add the milk, yogurt, water, and oil. Mix well making sure your yogurt, water, and milk are at room temperature.
Add it to the dry mixture and mix well with a whisk. The consistency of the dough should be slightly runny, but not liquidy.
Cover with foil or plastic and let it sit at room temperature for 1 hour. Do not leave it under a blanket.
Once an hour is over, use a piping bag fitted with a 1M star tip and fill it with the mixture.
Heat your oil (about 4 cups) on medium-high heat. Use a wooden skewer or a wooden spoon to test if it’s ready, if the oil bubbles around it, then you’re good to go.
Pipe the batter into a spiral shape starting from the middle and working your way out, then let it turn golden before turning and letting it get golden onto the other side.
Immediately, place it into room temperature qater/sheera and let it sit for a minute or longer, the longer it sits the sweeter and softer it gets.
Just like that they will be ready to serve and can stay good for a few hours.
