Not since Star Trek waffles (I’m not kidding) has a movie had so many unconventional food tie-ins as Captain America: The First Avenger. Clearly this called for a review in the interest of science journalism. So while visiting my parents for the Fourth of July weekend, I decided an expedition into patriotic tie-in food was required and resolved to try and review it all, a project which revealed one vitally important fact – apparently Americans really, really like patriotic donuts.
