Although I detest and reject every other edible plant in the Allium genus (such as onions, leeks, shallots, scallions, and chives), I have nothing but warm feelings for garlic (Allium sativum). I’ll cheerfully eat garlic in pretty much any form, any day of the year—bring on the bagna cauda, garlic fries, and even garlic ice cream. April 19 is National Garlic Day (for no readily apparent reason), a day to remember that garlic is effective at keeping away not just vampires and loved ones but also bacteria, high blood pressure, and possibly even cancer.
