Breaking into the squash was the hardest part of the entire process. Once split, I roasted it cut-side down to soften the flesh, and then mashed that into a browned butter bechamel base, enriched with egg yolks. I folded in chopped sage, grated parm, and a splash of good balsamic. Just before baking I gently nuzzled in whipped egg whites, put it into a hot oven for 35 minutes or so, and took out a puffed, browned on the outside, molten on the inside vehicle for turban squash goodness. Just don't try to wear it now.
