IF you are still able to afford the roast, this was a great recipe which I made in the North for our friend. Ask the butcher to remove the ‘ribs’ and tie them back onto the roast! While it was in the oven, I added parsnips, potatoes and some great heritage carrots (the multi-colored types) after dropping the temperature to 250 degrees. The ‘jus’ was wonderful!
PRIME RIB ROAST WITH MUSTARD & ROSEMARY CRUST
Jennifer MacKenzie (LCBO Food and Drink Holiday 2009)
With a simple mustard and herb seasoning, the wonderful beefy flavour of prime rib really shines. Searing the roast in a hot oven and then cooking it low and slow does take a little longer but it seals in every drop of juice keeping it melt-in-your-mouth tender. A good meat thermometer is worth the investment to make sure you get an accurate test for doneness. The slow roasting method reduces the quantity of pan drippings so the flavour of the jus relies on good-quality stock. Use homemade stock if you have it or the highest-quality prepared stock available. If you prefer thickened gravy, stir 2 tbsp (25 mL) all-purpose flour into the onions and cook for a minute before adding the stock.
