Refreshing Key Lime Pie vs Chelsea Buns

Both desserts rely on sugar, butter and egg, but put them to very different work. The Key lime pie binds graham cracker crumbs with melted butter and sugar into a baked crust, then whisks egg yolks with condensed milk and fresh lime juice into a tangy filling that sets with a slight jiggle and is served chilled. Chelsea buns work egg and butter into a soft, yeasted dough that rises twice, rolled around butter, brown sugar and currants. One is sharp, cool and creamy; the other warmly spiced, bready and fruit-studded.
