I prefer sweet potatoes baked in their jackets/skins until the sugar
oozes, good to do that on a foil lined pan or will be difficult to
clean. Scrub with a brush and pare away any rough hairy parts. We
eat the crisp skins, the best part. Marshmallows ruin the flavor of
sweet potatoes. I do like marshmallow cream/topping on a hot fudge
sundae. We also roast winter squash and enjoy their crisp skins too.
In fact we roasted a dozen butternut squash from the garden for dinner
last night and have the left overs to nuke... I'll eat them cold from
the fridge too. They are more flavorful when sliced lengthwise,
deseeded, seasoned with s n p, and grilled on the Weber. The Weber
was on for the sausage patties anyway. The hot squash only needed a
pat of butter. We try to pick the squash small but one or two always
get huge from hiding under the leaves... zukes do likewise. Zukes are
best grilled too. The new monster Weber grills lots of veggies, we
like grilled tomatoes, and I'll grill slabs of sweet onions for me.
I think we use the Weber more for veggies than for meats. Soon we'll
be grilling giant cabbage wedges.
