July 4th Food History: Smithsonian Shares Secrets Of Independence Day Favorites

Happy Independence Day!

As you sit down to a July 4th meal, have you ever given any thought to where those foods come from?

Experts at the Smithsonian Institution did, and they shared their findings in a recent blog post.

Hamburgers and hot dogs may seem all-American but pigs and cattle were brought to the New World by Spanish explorers; as Texas Parks and Wildlife notes,

As colonization increased, hog numbers subsequently increased. They provided an important source of cured meat and lard for settlers.

According to the National Hot Dog and Sausage Council, Americans will eat 150 million hot dogs over the Fourth of July holiday.

On the other side of the plate, tomatoes and potatoes have been a perfect pairing for centuries. As early as 1781, Thomas Jefferson served French-fried potatoes with tomatoes at Monticello; today, the average American consumes 142 pounds of potatoes and three bottles of ketchup a year.

As for that bun you're eating, wheat didn't come to the New World until Christopher Columbus sailed across the seas in 1492.

Jefferson aside, America's founding fathers enjoyed July 4th foods that aren't seen on most dinner tables today. John Adams, for instance, was a fan of turtle soup:

According to legend, on July 4, 1776, John Adams — who fought for independence and eventually because the second President of the United States — and his wife, Abigail, sat down for a celebratory meal of turtle soup, New England poached salmon with egg sauce, green peas, and boiled new potatoes in jackets. They followed the meal with Indian pudding or Apple Pandowdy.

What was served at the first Independence Day celebration? No one knows for sure but a Philadelphia chef told ABC News "the menu likely would have been based on the recipes of British culinary authority Hannah Glasse."

Glasse's July menu suggests the signers of the Declaration would have supped on roast turkey and fricasseed rabbit, pigeon, crawfish and lobsters. There would have been tongue and turnips and lamb testicles. And for dessert, apricot tarts and roasted apples, plums, jellies and custards.
