Refreshing Key Lime Pie vs Gypsy Tart

Both desserts rely on butter, but use it in opposite ways: the Key lime pie binds crushed graham crackers with melted butter for a baked crumb crust, while the Gypsy tart rubs cold butter into flour for a blind-baked shortcrust. The pie's filling of egg yolks, sweetened condensed milk and fresh lime juice bakes to a soft, creamy set and is chilled before serving, giving a bright, tangy finish. The tart instead whisks evaporated milk with dark brown sugar for fifteen minutes into a fluffy, coffee-coloured filling with rich brown-sugar sweetness and a slightly tacky top.
