Gallimaufric - Jumbled With Flair

I've been gobsmacked by a new word. Deep into John McPhee's The Deltoid Pumpkin Seed, the author hit me with gallimaufric. My eyeballs tripped over this vocabulary stumbling stone and tumbled into the gutter of white space between the lines. Here's the exact reference:

His ambitions and interests were, as they developed, gallimaufric. He invented, among other things, the combination lock.... He invented the wickless oil lamp. He invented a kitchen range for anthracite. As mayor, and also president of the board of health, he designed and built the Perth Ambroy sewer. In barracks constructed by the English Army in the eighteenth century he established workrooms for the manufacture of his inventions, which also included a fumigator, a forging press, a velocipede, a machine to crack nuts.

You get the idea.

Gallimaufric is the adjectival form of gallimaufry, meaning "a confused jumble or a medley of things," according to the New Oxford American Dictionary. Per various dictionaries, it refers to "a jumble or hodgepodge;" "a hash or ragout;" "mishmash or melange." (Incidentally, hodgepodge is an alteration of a Middle English term hochepot, meaning a stew. All these references to food are making me hungry!)

Unless you're a gourmand or Parisian expatriate, perhaps hodgepodge, medley, or jumble are more straightforward terms than gallimaufry. But what then would be the adjectival form? Hodgepodgy? Medleous? Jumbled would work, but it's kind of prosaic. Gallimaufric: now there's a word with panache! (Once you know what it means, that is.)
