你聽過“像餡餅一樣簡單（易如反掌）”這句話嗎？意思是某件事很簡單。但這可能會讓你疑惑，餡餅哪里簡單了？嗯，許多人倒是認為餡餅吃起來很方便。

餡餅是一種帶皮的烘烤食品。有時餅皮在底部，但在其他餡餅中，餅皮在頂部。有些餡餅甚至在頂部和底部都有一層皮。

古埃及人、希臘人和羅馬人都有各自的餡餅。他們把最初的餡餅做成盛放和烹飪肉類和其他食物的容器。餡餅皮可以當作一個盤子。早期的餡餅皮又厚又硬。人們經常吃餡料，但不吃堅硬的餡餅皮。

餅皮也保持了食物的新鮮。在冷藏后，餅皮能保存里面煮熟的肉，肉可以以后吃。餡餅也使熟食更容易保存。

隨著帝國的擴張，人們把餡餅帶到了世界其他地方，如拉丁美洲、中亞和東南亞以及菲律賓群島。廚師們用不同的配料制作了新型餡餅。在英國，廚師做肉餡土豆泥餅。它的表皮不是油酥皮，而是馬鈴薯皮。美洲定居者開始用新家園里種植的蘋果等水果做餡餅。

看到這么多餡餅，你可能會想到自己吃過的美味的餡餅。你接下來想要嘗試哪種餡餅呢？也許你可以和家人一起去當地的餐館，看看那里有什么樣的餡餅。
