By popular request, here's a recipe for my baked Sweet Potatoes:
2 large sweet potatoes (about 750g or 1.5lb in all)
2 tbsp brown sugar
1.5 tbsp balsamic vinegar
2 tbsp canola oil
half tsp salt
freshly ground black pepper
Pre-heat oven to 180 C (350 F). Meanwhile, peel your sweet potatoes and chop them into cubes of about 1 inch (no larger).
Take a baking pan that is long and shallow (e.g., 10in X 14in X 1in). Oil the base of it.
Dump all the sweet potato cubes in it. Now sprinkle over your brown sugar, balsamic, oil, salt and pepper. The salt is optional, of course.
Using two metal spoons, mix the sweet potatoes around so they become coated in the dressing.
After mixing, pat down the potato cubes into 1 layer over the base of the pan. This will help them to cook evenly.
Put the pan into the oven and roast for 45min to 1 hour.
At 1 hour, the cubes should look golden, glistening, and kind of shrunken: this means they will be extremely tender on the inside.
