There's hidden beauty inside many things, even ugly ingredients. In this pre-heat, the remaining three bakers have to use so-called ugly ingredients to make beautiful desserts. In the main heat, the focus is on geodes, which look like rocks on the outside but have beautiful mineral formations inside. The bakers are tasked with creating vibrant and colorful geode cakes using handmade rock candy to win the title of Spring Baking Champion and the $50,000 prize.
