Ingredients and substitutions for Pistachio Custard Bars
- Graham crackers: These the perfect base for these bars with their light and whole wheat flavor. If you are unable to obtain graham crackers, a great substitute in equal measure would be digestive biscuits or even oreos!
- Cocoa powder: High quality unsweetened cocoa powder is used here and works perfectly to compliment the flavors in the graham crackers.
- Sugar: The best sugar in the base is superfine or caster which helps dissolve into the crushed biscuit base. You could half and half the sugar with light brown sugar and caster sugar. For the filling, light and airy confectioner's or icing sugar works best to give a nice firm texture to that no bake custard.
- Butter: Unsalted butter is used for every stage of these bars, but if all you have on hand is salted, that works as a fine substitute, just leave out any salt suggested in the recipe.
- Pistachios: The absolute star of this dish is the pistachio paste you can make (or buy). Their flavor is unparalled when compared to other nuts so don't completely recommend substituting, however, you could try hazelnuts in place, if you prefer.
- Custard powder: This gives our bars a depth of flavor and smooths out the intensity of the pistachios. You could opt to leave this out, if you prefer.
- Salt & Vanilla extract: The flavor powerhouses, just a little of both of these adds a depth to the bars that creates a well rounded flavor.
- Dark chocolate: High quality dark chocolate was used here, the type you would snack on instead of baking chocolate due to it having less additives and leaving a more complimentary flavor to the bars.

FAQ's for the Pistachio Custard Bars
You need raw pistachios to begin with and for this recipe 140 grams, approximately 1 cup and will need to blanche them to peel fully.
This is done by boiling water and placing your pistachios into a rolling boil for 1 minute. Drain and wrap your pistachios in a clean dry tea towel, rubbing to dry and peel most of the skins off. You might have to peel some portions by hand.
Place into a blender and pulse, scrapping down the sides until you have a paste and the oils from your pistachios are visible. The pistachios might look like a paste and fine at the stage before the oils become visible, so keep pulsing and scrapping until you see the oils forming on the edges of your blender or food processor.
Set your pistachio paste aside where it will keep in a covered and dark space for up to 2 weeks. If you are adding this paste to a dish that doesn’t specify sugar, you can sweeten before finishing up by adding 50 grams / ½ cup confectioner’s or icing sugar to your blender once the paste is formed.
