Method
Lois is a slow-cook fan, simple good food, beautifully
cooked and simply presented, not over-adorned with garnishes or
needless decorations. To this end, Lois's slow roast fillet of beef
is an entertainer's dream. Cooked to pink perfection, and served
tiede, Lois can cook the meat in advance and enjoy her guests'
company without fretting over whether a costly fillet of beef is
cooked rare or medium. Lois says it's fail-safe. Cooked this way
the beef has an even pink blush throughout and a melt-in-the-mouth
texture.
Preheat the oven to 100°C. Spread the fillet thickly with the
mustard and place in a shallow roasting dish or deep-sided oven
tray.
Roast in the preheated oven for 2 hours. Remove and allow to rest
for 10 minutes before carving. The beef can be set aside, covered,
and served when ready.
