To make pistachio swirl fudge you will need:
- White chocolate chips
- Butter
- Salt
- Sweetened condensed milk
- Marshmallow creme
- Instant pistachio pudding mix
- Chopped pistachios
- Dark chocolate chips
The first thing that you need to do is line an 8 by 8 pan with heavy duty foil. I used my red and white Crow Canyon pan. I love the vintage look of there products. You can find this pan on Amazon.
Very lightly butter the foil and set the pan aside.
Next shell and chop your pistachios. For this recipe you will need approximately 1/2 cup of shelled and chopped pistachios. That’s roughly equal to two gas station snack (1.75 ounce) size bags of pistachios.
(And yes, I did use gas station snacks to make this fudge because the other bags of pistachios at the store were $8 and December is an expensive month!!) 
You’ll add the white chocolate chips, butter, salt, sweetened condensed milk, marshmallow fluff and instant pistachio pudding mix to a medium-sized saucepan and heat over low to medium heat.
Heat and stir until everything is melted and smooth. Reduce heat to the lowest setting and stir in the chopped pistachios. 
Meanwhile, melt 1 cup of dark chocolate chips in the microwave. The goal here is to have everything all hot and melted at the same time.
Pour the hot fudge into the prepared pan. Then spoon dollops of melted chocolate over the top. Use a toothpick or a butter knife to swirl the chocolate into the fudge.
Lightly tap the pan on the counter to remove any air bubbles and place in the fridge to chill completely. 
After the fudge has completely cooled and is firm to the touch, remove from the pan and cut into 1 inch squares. This recipe is an adaptation of a pistachio fudge recipe from The Lady Behind the Curtain.

I used Giardelli chocolate chips, and could not get them to "melt" so as to drizzle them. I had to milk to them. What brand of chocolate chips did you use?

Hi Dave, It sounds like your chocolate chips probably seized. It seems to happen more with chocolate chips than bigger pieces of chocolate and it occurs when the chocolate is over-heated or heated too quickly. Next time, you can try stirring in a teaspoon of boiling water and see if that brings back that melted chocolate texture we were looking for in this recipe. To answer your question about brands, I generally buy Tollhouse chocolate chips or Ghirardelli depending on what grocery store I'm shopping at, and think that both are good quality. I don't generally recommend store brands or off brands for chocolate chips.
Hope this helps! Amy D.
