Recipe Notes

How to Fry Perfect Donuts

👉🏻Let's start with the oil.  It's best to fry in oil that is very neutral and that has a "smoke point".  The smoke point is the temperature at which a given oil starts to smoke; it can catch fire if it gets much hotter than that.  Canola oil has been my favorite so far.  Peanut oil browned the donuts beautifully, but I didn't like the strong flavor that it left on my lovely spudnuts.  Check out Saveur for their article "Five Oils for Frying".

👉🏻Use a large heavy pot or dutch oven.  The pot needs to be deep enough to hold at least 2 inches of oil along with the frying donuts.  The pot should be able to hold around 2 quarts of oil.

👉🏻A clip-on thermometer to measure the heat of the oil is essential.  Here's why:  The oil needs to be heated to 350℉ and that temperature needs to be maintained throughout the entire frying process.  Don't worry if the heat goes up to 360-365℉.  Once the donuts are dropped into the oil the temperature may go down.  As long as the temperature is between 330 - 360℉, the donuts will cook perfectly.  If the temperature drops below 350℉, bring the temperature of the oil back up to 350℉ before frying additional donuts.

👉🏻Properly draining the oil from the donuts.  Each fried donut is actually drained three times.  First) When lifting the donuts from the oil, hold the donut above the pot and let the oil drip from the donut for about 10 seconds.  Second) Place cooked donut on a prepared baking sheet that has a few layers of absorbent paper towels.  Let the donuts to drain on the paper towels for 30-60 seconds.  Third) Remove the donuts from the paper towels and place them on a wire rack to completely cool.  This ensures a nice crisp outer layer that will absorb the glaze beautifully.
