These little citrus fruits, in season during the summer, pack a punch -- they have a more intense flavor than the more common Persian limes (which can also be used here). Shortbread stands in for the "crust," and a bruleed meringue topping completes the pie-like sundae.
If you love coconut-chocolate candy bars, this may be your dream dessert. Ice cream coated in shredded coconut is served with bourbon-spiked butterscotch sauce and a crunchy chocolate-almond topping. You will have more of the topping than you need -- and that's a very good thing, as it's also excellent on its own.
Smart Staple: Keep a box of puff pastry, which is the base for the sundae puffs, stashed in the freezer and you'll always be ready to make a decadent dessert. You can use any kind of fruit that's in season.
