This Beef & Guinness Stew is a wondrous thing – a rich, heady stew that rides the fine line between the richness of the gravy and slight bitterness of the Guinness; a stew that balances so closely neither sweet or bitter is detected; instead all melds into one glorious and delicious concoction. Even better, it’s topped off with puff pastry! (If you want to, and I know you do! Or maybe that’s just me?) Let’s just say if you do, you’ll look like a genius when you bring this to the table!
