Fillet of beef in a rosemary crust (Slideshow version)
Stage 11/12 : 30 min.
Cook the meat
Cook in the oven for about 30 minutes (just done) or 20 minutes (rare).For perfect cooking, it is best to use an electronic thermometer, stuck through the crust into the meat: at 140°F (60°C) it will be "medium", at 122°F (50°C) it will be "rare".
Break open the crust and discard it, then carve a thick slice for each guest.
