Preheat the oven to 200 ° C.
In a saucepan, mix the water with the oil and bring it to boil.
Meanwhile, in a large bowl, mix the regular starch with the sour starch and salt.
As soon as the mixture of water and oil boils, scald the starch, that is, pour the hot liquid little by little over the starch mixture. Stir well with a spatula until it has absorbed all the liquid.
Wait for the mixture to cool down before continuing to the next step. Otherwise, the eggs will cook and the cheese will melt with the heat.
When the mixture is cold enough, add the grated cheese and mix well.
Add the eggs and mix well until the dough has incorporated all the ingredients.
To shape the cheese bread, put a little oil in your hands, take some of the dough and make small balls. If the dough is too runny you can get the help of a scoop or put it in the fridge a little bit.
Bake it for about 30 min or until golden brown.
Serve it warm.
