Cook in batches
Sweet potatoes give off moisture and become soft when layered narrowly. A loose layer is crucial for the surface.
Food starch binds surface moisture and supports the crust. Because sweet potatoes contain more sugar and less starch than classic potatoes, they are cooked in a controlled manner at 190 °C.
Why this recipe works
Sweet potato fries are not as dry-crusted as potatoes' fries, but can browning strongly in the air fryer and remain soft inside. Even, rather thin pins and a loose basket filling are more important than additional oil.
Recipe
Sweet potato chips with a thin layer of starch, little oil and smoked peppers are cooked in portions and salted afterwards.
Peel sweet potatoes and cut them in about 8 mm thick, as even as possible. Put very thin tips aside or cook shorter.
Douse batons dry with kitchen paper. In a large bowl, mix with starch until only a thin layer is visible.
Add rapeseed oil, both varieties of pepper and garlic powder and mix thoroughly. The salt remains outside.
Preheat air fryer to 190 °C. Fill the sweet potato pins in a loose position and work in two portions if necessary.
Cook fries for 10 minutes, shake vigorously and cook for another 6 minutes. Turn again and cook for 2 to 4 minutes until the desired browning.
Salt ready fries immediately. If desired, mix yoghurt with a splash of lime juice and serve as a cool dip.
Kitchen know-how
Sweet potatoes give off moisture and become soft when layered narrowly. A loose layer is crucial for the surface.
Sweet potatoes can get dark early on thin tips. From minute 16 on, check frequently and remove finished pieces.
A thick, stained layer of starch remains floury. Dry the batons first and use only so much starch that they are hardly visibly coated.
