I have just boiled a batch and can recommend boiling over roasting.
Boiling provides even cooking - ie - no hard bits, just an even tasty soft sweetness.
I intended to mash but they are so soft I didn't need to.

You need asbestos fingers because they need peeling while still hot. As they cool and dry they become harder to peel. They peel easier than roasted because the shell is softened by the water.

You need to 'score' the shell before boiling just the same as when you roast (prevents explosions) - a 20 min boil was enough
