In a bowl, combine crabmeat, yogurt, chives, dill, lemon zest, olive oil, garlic and salt. Dollop the crab salad onto each crostini, then top each mound with caviar.
Budino in Italian means pudding but this is more like a molten cake, moist and almost gooey in the middle when served warm from the oven. I like to serve the budino with a scoop of homemade Banana Chocolate-Chunk Ice Cream (in my cookbook, Cooking From the Hip), but it's also great with creme anglaise and fresh raspberries or strawberries.
