Oh sorry about that am being a bit absent minded at the moment .
Here you go
8 cloves garlic
45 ml olive oil
680 g potatoes, peeled and cubed
680 g sweet potatoes, peeled and cubed
120 ml milk
55 g butter
0.5 g dried rosemary
50 g grated Parmesan cheese
salt to taste
ground black pepper to taste
Preheat oven to 175 degrees C. Put garlic in small ovenproof bowl, and drizzle with olive oil. Roast for 30 minutes, until very soft. Cool, peel, and reserve oil. OR CHEAT AND USE READY MADE GARLIC OLIVE OIL
Cook potatoes and sweet pots in a large pot of salted water until tender, about 20 to 30 minutes. Drain, reserving 1 cup liquid.
Place potatoes in a mixing bowl. Add milk, butter or margarine, rosemary, garlic, and reserved olive oil. Mash until smooth as desired, adding reserved cooking liquid as needed. Mix in some of the cheese. Salt and pepper to taste. Transfer to a buttered or oiled baking dish. Sprinkle with remaining cheese.
Bake for 45 minutes, until heated through and golden on top. OR PLACE IN DISH AND INTO FRIDGE A FEW DAYS BEFORE ON THE DAY BRING TO ROOM TEMP THEN INTO OVEN OR UNDER A GRILL FOR 20 MINS
I like it because I do it in advance and put it in when turkey comes out - is not overly garlic and very very yummy.
