I'd love to see a dual-purpose item called a Freezy Bake Oven that will make both hot and cold items.
Perhaps have two skills required:
Pastry Cheffery
Gelato Mastery
Possible recipes for Pastry Cheffery: Pies, cakes, cookies, quiches, puddings, casseroles, lasagna
Possible recipes for Ice cream treats: Ice creams, gelato, sorbet, popsicles (require wood planks and fruit?), mochi balls, frozen fruits
