I am only making one batch this year, so I chose to leave out the nuts.
Fudge
1 1/2 cups sugar
1 can evaporated milk
1/4 cup butter, cut in pieces
1/4 teaspoon salt
2 cups mini marshmallows
12 oz. semi-sweet chocolate chips
1 teaspoon vanilla
1 cup walnuts or pecans, chopped (optional)
Cut up half a stick of butter and place it in a large glass bowl. Use the other half of the stick to grease a 9X13 non-stick baking pan. Set the pan aside.
Put the sugar, salt and milk in the bowl with the butter and cover it with a piece of wax paper. Microwave on high for 3 minutes.
Remove the bowl, discard the wax paper, stir and put it in the microwave for 10 more minutes. Stop the microwave every 3 minutes to stir. After 10 minutes, check the temperature. it should be between 234°-240°. My thermometers never rise fast enough to catch the real temperature, because the sugar solution is rapidly cooling off. If it is at 230°, you are good.
Add the chocolate chips to the hot sugar and stir until melted. Then add the vanilla and the marshmallows. Stir until melted. You may add the nuts at this time if you desire. Stir until glossy.
Spread in the pan. You can chill it, or just let it set out for several hours. Slice with a knife that will not cut your pan. I have a plastic one for that purpose. Store in a covered container. Put it high on a shelf until company arrives or they will not get very much.
