I've just done a load. Had a disaster at first... didn't realise the site was using farenheit instead of centigrade... and had black crispy fruit which I had to chuck
I bought a bag of value oranges, one of lemons, some limes and used up the leftover fruit that was bit past it (strawberries and apples).
Cut the fruit about 3mm thick. Put on a wire rack above a baking tray in an over at about 50-60 degrees C.
Turn over after a couple of hours, then take out after a couple of hours. Any fruit not completely dry pop back in. Oranges take longer than everything else.
Tesco do big cinamon sticks for £1 from the East End (or similar) company. They look pretty but don't smell unless you break them.
I have added a couple of drops of orange essential oil to my dried fruit which seems to work well. You literally just need one or two drops.
You can then glue them together for decorations and add ribbons or chuck in a bowl as potporri. If you do that add a few cloves, a bit of powdered cinnamon and a grating of nutmeg. You can add ground Orris root too if you can find it.
