We planned to do Roast beef for lunch tomorrow and bought a joint last week from asda. It is labeled as great for roasting and is a silverside joint. Now all my books (that I consulted after buying said meat) talk about silverside as a joint for boiling or salting (not what asda reckons). I'm still willing to give the roasting a go, but I'm a bit concerned that it doesn't have much fat around it - does this mean that it will get very dry? Wwhat can I use to make it less so? Do I drizzle it with oil or smear with butter? what?
