Eggs represent spring and new beginnings better than anything else, and because eclairs use a lot of eggs, the seven bakers take on springtime eclairs in this pre-heat challenge. Then host Ali Khan asks the bakers to create edible spring goodie baskets filled with two types of baked treats -- one of which must use a hard-boiled egg.

What makes desserts sweet? Usually it's sugar, but in the desert, it's agave. For this pre-heat, the five bakers must use only agave as the sweetener in an assigned dessert -- a tart, a flourless cake, an ice cream sandwich, a doughnut or a cupcake. For the main heat, the bakers make succulent cakes that rival the real thing.
