will have to grow them to try your trick. i do love them, but in our grocery, they are all wax covered, so have to be peeled to cook them. i do sweet potatoes and small winter squash in the oven or microwave all the time then scoop out the cooked flesh.

i’m going to comment on using a knitting needle to test “food cooked” – i have a couple in my kitchen which i used to use for cakes/baking –
