Sweet Potato and Lemon Salad

This is my translation of a yummy salad I've had cooked for me a couple of times by a young Japanese girl who lived with us. I wish you could see the original.

• Ready In: 35 mins
• Serves: 6-8

Ingredients

• 4  sweet potatoes (about800g)
• 2  lemons, scrubbed,peel left on
• 200  g sugar

Directions

1. Peel the sweet potatoes, and slice lengthways.
2. Cut into 1cm half moons.
3. Do the same with the un-peeled lemon.
4. Place all the ingredients in a saucepan with almost enough water to cover.
5. Bring to the boil, and then reduce the heat and simmer (don't cover the saucepan) until most of the liquid has boiled away and the potatoes are soft.
6. Cool to room temperature and serve.
