How Leonardo da Vinci used rudimentary pigments in 1503 to create such subtle shadows and light on the Mona Lisa has long baffled art historians. Now, French researchers are using X-ray fluorescence spectroscopy to isolate and study each ultra-thin layer of paint and glaze da Vinci used to create the effect he was seeking, according to recent news reports.
By beaming x-rays on the Mona Lisa without removing it from the wall on which it is mounted in Paris' Louvre Museum, scientists found that da Vinci used a Renaissance painting technique known as sfumato, intricately mixing thin layers of pigment, glaze and oil to create the appearance of lifelike shadows and light. Scientists now believe that da Vinci used up to 30 layers of paint on his works.
While this may solve one mystery about the Mona Lisa, others remain, like: who is this enigmatic woman and why does she hold her subtle half-smile? To these questions we can add another: what did this mysterious woman and da Vinci like to eat?
According to one researcher who studied the culinary habits of Renaissance Italy, some favorites included Risi e Bisi, Saffron Risotto with Duck and Mushrooms, and Spinach Soup with Hazelnuts. Although those recipes would be impossible to duplicate today, this one for Mushroom Risotto from the New York Times might give you a sense of how and what Leonardo da Vinci liked to eat!
4 cups beef or chicken stock
1/8 teaspoon ground saffron
3 tablespoons unsalted butter
2 tablespoons olive oil
1/4 cup finely minced scallions
1/4 cup finely minced onions
1 pound fresh wild mushrooms, trimmed
1 1/2 cups Italian Arborio rice
Salt and freshly ground black pepper to taste
3/4 cup freshly grated Parmigiano-Reggiano cheese
Place stock in a saucepan and over medium heat bring to a simmer. Add saffron, stir, and simmer slightly. Meanwhile, in a saucepan over medium heat, melt 1 tablespoon butter in olive oil. When foam subsides, add scallions and onions and cook until softened and yellow but not browned. Add mushrooms and saute, stirring occasionally until liquid has evaporated.
Add rice to mushrooms, and cook, stirring to coat well, with butter and oil. Add approximately 3/4 cup of simmering stock to rice and mushrooms. Stir well and continue to cook, stirring occasionally, until rice has absorbed most of stock. Continue adding stock to rice by half-cupful adding only after rice has absorbed previous addition.
As cooking continues, stir more frequently. After 25 minutes, rice should be tender but still chewy. Remove from heat. Add salt and pepper to taste. Stir in remaining butter and 1/4 cup of Parmigiano-Reggiano. Serve immediately, passing the rest of the cheese.

Abraham Lincoln Kentucky Corncakes
Another was a wild turkey named Jack with whom Lincoln’s youngest son Tad played with daily. When it came time for Jack to be sacrificed for a holiday dinner, Tad supposedly begged his dad to spare the turkey’s life, and, to this day, the White House maintains the tradition of “pardoning” a wild turkey each holiday season!
Although it’s a "tad" early to be thinking about preparing your next holiday dinner, you can whip up a batch of Kentucky Corncakes, which are a great side dish at just about any meal and were a Lincoln family favorite. If you’d like to make some Kentucky Corncakes today, here is a simple and simply delicious recipe to try from the Food Network:
1 cup roasted cornmeal (fine ground yellow cornmeal)
1 cup self-rising flour
4 tablespoons sugar
2 eggs
2 cups buttermilk
3 ounces corn oil
2 cups fresh corn kernels
Place cornmeal, flour, and sugar in a bowl and mix together. In a separate bowl, combine eggs, buttermilk, corn oil, and fresh corn and mix together. Fold mixtures together. Place 4 ounces of pancake mix onto a hot griddle. Cook on medium high heat for 4 minutes on each side, until cooked through. Serve warm with lots of butter and honey enjoy!
FAST FACT: According to historians at the Miller Center, the Lincoln family's routine in the White House reflected "the presence of their sons, the demands of war, and the highly complex and many-sided character of Abraham and Mary. [T]he day went from breakfast together as a family at 8:00 in the morning, reunion again for dinner at 8:00 in the evening, and then bedtime. Until little Willie's death in 1862, the two younger sons demanded a good deal of attention, and both parents gave them ample attention, although Lincoln grew more distant as the war progressed and occupied much of his day."

James Garfield, the Pythagorean Theorem, and the Founding Father of Vegetarianism
As you might recall from grade school, the theorem says that in a right triangle, the sum of the squares of the two right angle sides will always be the same as the square of the hypotenuse (the longest side).
Translated mathematically, the equation would read: A2 + B2 = C2. Let’s try it quickly here: If Side A is 4 inches long and Side B is 3 inches long, the equation would be: 4 x 4 = 16 and 3 x 3 = 9. Added together, 16 + 9 = 25. Now we simply find the square root of 25 and - voila! - we know that side C is 5 inches long!
So what does the Pythagorean Theorem have to do with food? A lot, if you consider the fact that Pythagoras has been called the Founding Father of Vegetarianism. Until the 19th century, when the term "vegetarian" came into use, people who didn't eat meat were often called “Pythagoreans.”
As a young man, Garfield was a farmer in Ohio and wouldn't have called himself a Pythagorean, but he might have enjoyed this healthy recipe for Ultimate Veggie Burgers from 101 Cookbooks if he tried it!
2 1/2 cups garbanzo beans or canned garbanzos, rinsed
4 large eggs
1/2 teaspoon fine-grain sea salt
1/3 cup chopped fresh cilantro
1 onion, chopped
Grated zest of one lemon
1 cup toasted (whole-grain) bread crumbs
1 tablespoon extra-virgin olive oil
Combine garbanzos, eggs, and salt in a food processor. Puree until the mixture is the consistency of a thick, slightly chunky hummus. Pour into a bowl and stir in the cilantro, onion, and zest.
Add breadcrumbs, stir, and let sit for a few minutes. Heat oil in a skillet over medium low, add 4 patties, cover and cook for 7-10 minutes. Flip the patties and cook the second side for 7 minutes, or until golden. Remove from the skillet and cool on a wire rack while you cook the remaining patties.
FAST FACT: Garfield was one of our most intellectual presidents. Before going into politics, he was a professor of ancient languages. He was also ambidextrous and it has been said that he would often show off his knowledge by writing Greek with one hand and Latin with the other. Now THAT'S impressive!
