>A very good friend on here and twitter, Allotment Ali, has been experimenting with Sweet Potatoes this season so I have posted this recipe for her.
Anyone who likes the idea of growing these delicious tubers should read her blog.
Sonia’s Leek and Sweet Potato Gratin
400g leeks, trimmed and washed
750g sweet potatoes, peeled and very thinly sliced
1 tsp paprika
300ml single cream
1. Finely slice the leeks. Melt a third of the butter in a frying pan, add the leeks and cook until just tender. Preheat the oven to 190c/170c fan/gas5. Grease a shallow ovenproof dish
2. Sprinkle a layer of leeks in the bottom of the dish. Top with a layer of sweet potatoes and sprinkle with a little paprika. Repeat, finishing with a layer of sweet potatoes.
3. Pour over the cream and dot with the remaining butter. Loosely cover with foil and bake for one hour, removing the foil for the last 10 minutes for a crispy outer layer.
