This came as a "why not" moment when I pouring a HB while I was cooking dinner. At first I was worried that I'd gone overboard (~350ml went in), but after it cooked down it was great.
Piggy's Pasta Sauce is usually a rich tomato based sauce with veges, olives, and fresh herbs. Now it has a hint of a malty taste in the background. Top Stuff (all though I'll admit maybe not for everyone)
P.S. It's not beer, but it's a recipe (sort of) so I put it here
