What is a good way to cut potatoes into wedges?
Clean your potatoes. Peel if desired.

Slice in half, lengthways.

Place flat sides down on your cutting board. Cut again in half, lengthways. This would be for very large wedges. For slightly smaller, cut in thirds, lengthways, on a 60 degree angle, from the outside of the potato to the centre line where it hits the cutting board.

For even smaller, slice in half again after the second half cut.
