Preheat the oven to 310 degrees F.
Put 1 and 1/2 cups shelled pistachios into a cuisinart.
Coarsely grind. Remove from the Cuisinart and put aside.
Measure 3/4 cup of almonds into the cuisinart.
Grind to a very fine consistency. This should take about a minute.
Separate 2 egg whites from the egg yolks
Put the 2 yolks in the bowl of a mixer. Add 2 full eggs.
Add a 1/2 cup ad sugar and blend until fluffy.
Add the ground pistachios and almonds, 1 tablespoon cocoa powder, and 3/4 cup chocolate chips.
Mix until everything is well combined. The mixture will be chunky. Set aside the mixture.
In a clean bowl, using the whisk attachment, beat the 2 egg whites with the remaining sugar. Soft peaks will form.
Fold the egg whites into the nut mixture.
Stir in 1 and 1/2 tablespoon of melted butter.
Pour the batter into a well greased loaf pan. Bake for 40-50 minutes, or until a toothpick comes out dry. After taking out of the oven, remove the cake from the loaf pan to cool.
I like to slice up the loaf so that it is easy for guests to grab a piece.
Serve at room temperature, with a little powdered sugar sprinkled on top. Recipe taken from The Book of New Israeli Food: A Culinary Journey by Janna Gur.
