'profiteroles' on Serious Eats
I was thrilled when I came across these Beer Profiteroles with Chocolate-Beer Sauce in The Boozy Baker by Lucy Baker. They weren't just profiteroles, but a tasty grown-up version made with a dark beer ice cream and finished with chocolate beer sauce. This is a recipe for anyone who has ever experienced the pleasure of a stout float or Guinness milkshake. Dark beer, chocolate, and ice cream are pretty much made to go together.
