1.Preheat oven to 200°C/400°F.
2.Place one sweet potato on an oven tray. Bake for 1 hour or until tender; cool. Reduce oven temperature to 160°C.
3.Meanwhile, peel remaining sweet potatoes. Using a mandoline or V-slicer, cut sweet potatoes lengthways into 3mm thick slices. Trim slices into 6cm x 12cm rectangles; you will need 36 rectangles.
4.Bring a large saucepan of water to the boil; season with salt. Add half the sweet potato slices, boil for 1½ minutes or until softened. Remove from pan with a slotted spoon; place on a tray to cool. Repeat with remaining sweet potato slices.

6.Grease a 4-litre (16-cup) shallow ovenproof dish (or two 2-litre (8-cup) shallow ovenproof dishes). Place 1 heaped tablespoon of filling mixture at the short end of a sweet potato slice; roll to enclose filling. Place, seam-side down, in dish. Repeat with remaining sweet potato slices and filling mixture, until dish is filled in a single layer.

8.Bake for 15 minutes or until top is golden and crunchy.
