Microwave a few strawberries in a bit of water to soften and release their juices. Mash well.
In a microwave safe bowl, combine flour, sugar, water, milk, pureed strawberries and drops of oil. Mix until well-combined.
Cover with plastic wrap or a microwave safe lid. Microwave for 2 minutes. Remove and stir the mixture well with a wooden or metal spoon. Repeat 2 more times for a total of 6 minutes in the microwave. The dough should come out stretchy.
Let the dough rest until cool enough to handle. You may put it in the fridge to speed up the process.
Spread some cornstarch on a cutting board or counter and coat the sticky dough.
Divide it into 12 pieces and shape into a flat circle. Add about ½ teaspoon of jam to the center of each disc. Pull the edges of the dough to wrap together to cover the filling, pressing the edges together to seal well. Use more cornstarch as needed if too sticky.
Store at room temperature for a few days or freeze it for longer storage, ensuring it's thawed before consumption.
