This winter stew with beef and root vegetables ('runderstoofpotje met bokbier en wintergroenten') is enriched with 'bockbier'. This reddish-brown seasonal beer, (called 'bokbier' in Dutch) is popular in the fall and winter months in the Netherlands, and is not only great for drinking but also adds a bittersweet malty flavor to your cooking. If you can't find Dutch bockbier where you live, substitute it with brown ale.
Celery leaf is commonly used as a herb here in Holland (it is called selderieblad in Dutch). If it's hard to find where you live, simply buy a bunch of celery and use the tender interior leaves. It won't be quite as green, but it will taste pretty much the same. Stews are a fantastic way to use up leftover bits and bobs in the fridge. So, if you have extra root veggies that need to be used up before they turn, feel free to throw them in. This dish can easily be prepared a day in advance and heated up when needed. As with most stews, it's even better the next day.
