I'm afraid your research is not novel NomNomNom. I'd succeeded in achieving the same more than twenty years ago using a lemon meringue pie containment structure. The lower thermal conduction coefficient of the superstrate and remarkable thermal capacity of a curd-based interior more than compensated for the slightly inferior efficiency of the primitive apparatus of the era. Sadly that avenue of investigation will lead you to ruin. Stop before it's too late. The process yields a horrendous endothermic form of fusion and the cleanup liabilities are unbearable.
