Columbus and his men, on entering the New World, also entered a whole new world of food. In Spain and in Europe in general, they would have eaten, say, turnips, onions, garlic and carrots.
By the early 1500s, Columbus was probably dining on tomatoes, maize corn and sweet potatoes, all of which had been cultivated in South America for many years.
Hard to imagine Spanish and Italian cuisine without the tomato (which is actually a fruit, to be technical), but there it is.
Last on our list is a cooking component that many cultures can't do without: spice.
For a commemorative meal…
Consider trying maize (if you can find it) or go with sweet potato pie, a corn-and-tomato salad, or, to meld the two worlds, a garlicky tomato sauce.
