Hi shivvy. I love homemade wedges. I just use plain old white spuds, cut them into wedges of equal size so they cook all at once. put them on a baking tray, drizzle quite generously with olive oil, season with salt and a bit of black pepper.
Put in the oven at about 200 degrees C. I don't really time stuff, I just check every so often. The wedges I do usually take about 40 mins. When they look sort of crispy and delicious they are ready!
I am not good at giving "directions", so I hope I haven't baffled you! x
