Preheat the oven to medium (180°C)
Prepare the filling: In a saucepan, mix the milk with the vinegar and bring to a simmer without letting it boil, until the milk curdles
Remove from heat and let it sit for 30 minutes
Strain through a cheesecloth
Fold it into a sac-like shape
Place it under running water for a few minutes
Squeeze gently and hang it over a faucet to drain completely
When the dough is well dried, remove it from the sac and knead it until it's fine
Add the egg yolks, egg white, sugar, butter, and flour and mix well
Place the mixture in a saucepan and bring to a simmer, stirring occasionally, until boiling
Remove from heat and let it cool slightly
Then pass the mixture through a fine-mesh sieve
If making the dough ahead of time, keep the mixture refrigerated
Prepare the dough: Place the flour in a bowl, make an indentation in the center and add the egg yolks, butter, sugar, salt, and warm water
With your fingers, mix the flour delicately until you get a pliable dough that can be opened
If necessary, add a little more flour
Cover with a cloth and let it rest for 30 minutes
Open the dough very fine and line mini muffin tin cups with capacity of 4 tablespoons of water
Add the filling and bake in the oven for 45 minutes
After baking, unmold the cottage cheese fritters and dust them with confectioner's sugar.
