Wonderful Fudge

This is my mother-in-law's recipe. I think it's the best.

1/2 c butter 

1 can (14 1/2 oz)                     evaporated milk 

4 1/2 c sugar

1/2 lbs marshmallows
2 oz unsweetened choc.
12 oz semi-sweet choc.
3 (4oz) bars german choc.
1 T van.
2 c chopped nuts

Over moderate heat, combine and melt butter, sugar and milk, bring to a boil for 5 minutes, stir, then turn off the heat add marshmallows and stir until melted. Then add each different  broken up chocolate one at a time, stir until melted. Stir in vanilla and nuts. Pour into 10x15 buttered pan. Let stand until firm. Cut into 1 in. squares.

It is not necessary to use the 3 chocolates above but use 26 oz. of your choice of chocolates.

My mother-in-law used 2 lbs(8 cups) pecans.
I use 1 lb (4 cups.)
