Cousin Maria's Skordalia (Garlic spread)

5 medium potatoes
1 whole head garlic, thru the press
18 oz. canola oil
1/2 cup white vinegar
salt to taste
1 egg
Peel potatoes and cut into bite size chunks and cook in boiling water (like mashed potatoes). When cooked, drain water and mash and salt potatoes. Remove half then add garlic. Then add back potatoes alternating with oil and vinegar til all back in pot mixing with mixer after each addition. Add egg and beat at high til fluffy. Add more salt if necessary. Serve with sliced French bread. Or anything else...great with vegetables, seafood, meat, whatever. I actually got this recipe from Mary Mandalou.
