Sweet Potato Fries

1. Peel the sweet potatoes and cut them into even, finger-thick batons.

2. Soak in cold water for 20 minutes to draw out the starch, then dry completely on a tea towel.

3. Dust with a little flour to help them crisp.

4. Toss thoroughly with the oil, smoked paprika, salt and pepper.

5. Spread on a lined tray in a SINGLE layer, well separated – this matters most.

6. Roast at 220°C for 25-30 minutes, turning halfway.

Tip: Overlapping fries steam and go soft. Use two trays rather than crowding one.
