First things first, A TOMATO IS A FRUIT! It’s considered a fruit because it is “a berry, consisting of the ovary, together with its seeds, of a flowering plant” (Wikipedia). Tomatoes are native to South America, and they were brought to Europe by the Spanish, where they slowly grew in popularity. Tomatoes were first seen as poisonous, as they are in the nightshade family (Wikipedia). The acidity in them caused the pewter plates used at the time to tarnish, furthering the fear that they were poisonous. Over time, the fruit was accepted as an essential food in worldwide cuisines. A tomato is 95% water, making it extremely juicy (Wikipedia).
The tomato pie is truly a southern treat. The earliest recorded recipes--the earliest being the 1800s--are sweet versions, using green tomatoes in the similar manner to an apple pie. The tomatoes could be seasoned with sugar, butter, cinnamon, nutmeg, and other warm spices. The unripe tomatoes are more firm, and taste similar to an apple. Later, in the 1900s, the savory version became more popular. Traditionally, it is made only during the height of the tomato season (late spring through the summer) when tomatoes are at their best. It typically includes basil and/or other fresh herbs, topped with a creamy cheese mixture. This mixture can be mayonnaise based, or white-sauce based (like a bechamel). There are also usually onions thrown in, specifically Vidalia onions. This pie may seem a bit odd to non-Southerners (and some Southerners too), but it is a must during the super hot summers. Order one today before the end of the summer!
TL;DR: This pie is made of fruit, fruit is healthy, therefore, pie is healthy. Be good to your body and order a pie!
