Operating without a deep-fryer requires strict attention to thermal recovery rates and oil volume, meaning two inches of neutral oil in a heavy-bottomed Dutch oven is the absolute minimum requirement to prevent the dough from touching the bottom and burning before the crust can set. When you dump raw starch and boiling liquids together over medium heat, gelatinizing the flour completely before the eggs go in ensures the piping bag holds its structural integrity under pressure. Most cooks fail here by rushing the cooling phase, forgetting that adding whole eggs to piping-hot batter will prematurely curdle the proteins and ruin the piping consistency.
If your frying thermometer breaks or you simply refuse to use one, drop a small one-inch cube of white bread into the oil once the surface shimmers; if it turns golden brown in precisely sixty seconds, the temperature sits safely between 350 and 375 degrees Fahrenheit. Anything slower means your churros will absorb excessive fat and turn soggy, while bread that chars instantly indicates the fat is scorching hot and will burn the exterior before the raw interior cooks through. Monitor the bubbling intensity around the piped dough as it hits the pan, looking for steady, aggressive agitation rather than violent sputtering.
