Deep Frying at Home
Frying is less about submersing food in fat and more about managing thermal energy. When done correctly, the crust is crisp, shattered, and entirely distinct from the moist interior.
Control the heat, control the outcome.
Use a thermometer. Relying on visual cues like bubbling or smoking points is a gamble that leads to either undercooked centers or burned exteriors.

Maintaining thermal momentum
Oil loses heat the second you add cold food; if you don't keep the flame high enough to bring it back to temperature quickly, the food will boil in the oil rather than fry.
The method.
Prep the station
Place your wire rack over a baking sheet. Fill your pot no more than halfway with oil, leaving at least 3 inches of clearance at the top to account for bubbling and splashing.
Monitor the heat
Bring the oil to 365°F over medium-high heat. Clip your thermometer to the side of the pot so the tip is submerged but not touching the bottom.
Add in stages
Lower food gently into the oil using a spider skimmer. Do not drop it from height. Add only a few pieces at a time to prevent the temperature from dropping below 330°F.
Manage the cook
Adjust the heat as needed to keep the oil within the 350-375°F range. Flip pieces once if they are fully submerged, or occasionally to ensure even browning.
Drain and season
Remove the food when it is deep golden brown and sounds hollow when tapped with a utensil. Place on the wire rack and salt immediately while the surface is still hot enough to absorb the seasoning.
Other turns to take.
Battered
Whisk flour and cold carbonated water or beer until just combined; the bubbles create pockets of air that result in a lighter crust.
Dredged
Coat in seasoned flour, shake off the excess, and let sit for 10 minutes so the moisture creates a 'glue' that ensures the coating sticks.
When it doesn't go to plan.
Pat food dry with paper towels before frying; moisture is the enemy of a crisp crust.
Never leave a pot of hot oil unattended.
If the oil starts to smell acrid or looks dark and murky, it is past its prime and should be discarded.
Always turn the handles of your pot inward toward the stove to avoid accidental spills.
The ones that keep coming up.
Why is my food greasy?
The oil temperature was likely too low. If the heat isn't high enough, the oil permeates the food instead of being pushed away by the rapid release of steam.
Can I reuse the oil?
Yes. Let it cool completely, strain it through a fine-mesh sieve or cheesecloth to remove food particles, and store it in a sealed container in a cool, dark place.
