An amateur cook hits a new high when he/she makes their first roast beef. This classic reserved-for-holidays meal is a nostalgic standby that conjures everything homey, comfy and happy.

According to Quilter, the fool-proof roast beef has A LOT to do with the type of joint you buy, the temperature you change halfway through cooking it, and the time you wait before you carve it.
