Think of John Collins as a lesser-known sibling of the popular Tom Collins. Believed to have been invented in the late 1800s at Limmer’s Old House in London, the cocktail was reportedly named after the head waiter at the establishment. Silent film actor Frank Sheridan even wrote a rhyme dedicated to John Collins, whoever he may be.  Despite its unclear origins, John Collins became a distinct version of the classic Tom Collins. Both are made with lemon juice, club soda, and simple syrup, but what sets them apart is the spirit used. The former substitutes gin for whiskey, giving it a distinct golden-yellow hue.
