The details that decide it
Why pistachios are so green — and what the colour tells you
The green in a pistachio kernel comes from chlorophyll, the same pigment as in leaves, and it is most intense in nuts grown in cooler conditions. The colour fades with age and heat, so a bright green kernel is a sign of freshness while a dull, olive, brown-flecked one has been sitting around. Freezing holds the colour as well as the flavour, which is why a frozen bag of kernels looks better on a plate of ice cream than a pantry one of the same age.
- The green is chlorophyll, and it fades with age and heat.
- Bright green kernels are the fresher ones.
- Freezing preserves both the colour and the snap.
Salted in-shell pistachios and the freezer
Salted, roasted in-shell pistachios are the snack form, and they freeze fine, but the salt and the shell are not what you want if the nuts are headed for a dessert or a crust. Shell them first if you plan to bake, because the salt will throw off a sweet recipe, and freeze the kernels in a small bag. The shells themselves can be saved for stock, where their faint nuttiness adds depth.
- Snack pistachios are salted — shell them before baking.
- Salt in a crust or dessert throws off the recipe.
- The empty shells add a faint nuttiness to stock.
Freezing pistachios for crusts and ice cream
Pistachios are chopped or ground for crusts, folded whole into ice cream, or blitzed into pistachio butter, and the freezer suits all three. Freeze whole kernels and chop them cold when you need them, so the pieces stay distinct rather than turning to paste. For a crust, blitz frozen kernels with a little sugar and flour to keep them dry, and freeze any extra pistachio butter in small jars.
- Chop cold kernels so the pieces stay distinct.
- Blitz with a little sugar and flour for a dry crust mix.
