Ingredients and substitutes

This biscotti recipe is made from a simple dough, enhanced by fragrant lemon zest and mixture of pistachios and almonds. Here's what you will need, and some swaps you can make to customise this bake:

Caster sugar - as always, I use caster sugar in most of my bakes, as it has finer texture. But traditional, white granulated sugar will work just as good.

Eggs - Use large eggs, make sure they are at room temperature before using them in the recipe.

Almond extract - adds wonderful aroma and enhances the flavour of these cookies/ biscuits . If you don't have any almond extract, you can simply add teaspoon vanilla instead.

Olive oil - use mild-flavoured olive oil or replace it with melted and cooled unsalted butter.

Limoncello - the addition of this Italian liquor elevates the lemon flavour even more, but it's totally optional. If you don't want to use it, just skip it. You can also add 1 teaspoon of lemon extract or 1 teaspoon of lemon juice instead.

Pistachios - use shelled pistachios. If you want, you can chop them roughly, but I never bother. If you are not a fan of pistachio nuts, stick to almonds only.

Almonds - it is best to use whole almonds, but you can use blanched almonds too. As with pistachios, there is no need to chop them.

Flour - plain, all-purpose flour is used in this recipe, but you can also experiment with different types of flour here. This recipe will also work with gluten-free flour.

Baking powder - you can substitute baking powder for ¼ teaspoon of baking soda.

Cardamom - I just adore the fragrant and flavour of this spice, but you can swap it for cinnamon, nutmeg or allspice. Or just skip it completely if you are not a fan.

Lemons - I used my favourite Sorrento lemons, which are extremely aromatic. The lemon peel on this verity is also very rich in natural lemon oil. You will need at least 2 tablespoon of the lemon zest. Any type of unwaxed lemon will be fine to use.

How to make biscotti

Place all the dry ingredients and lemon zest in a bowl and mix to combine. In a separate bowl, using a hand-held electric mixer or kitchen whisk, beat together the eggs, sugar, almond extract, olive oil and limoncello, until you have pale and fluffy mixture.

Add the pistachios and almonds to the egg mixture and mix it all together. Tip the dry ingredients into the bowl with wet ingredients and fold until well combined.

Transfer the dough onto well floured surface, and divide dough in half. Using lightly floured hands, shape the dough into two logs and transfer them into baking sheet. Bake until golden brown and crisp on top.

After first bake, remove them from the oven and cool on a wire rack for about 10 minutes, or until the logs are cool enough to handle. It's important not to leave them to cool for too long, as these pistachio biscotti will become harder and more difficult to cut. They may also start snapping and breaking when you start slicing them, so make sure you stick to 10 minutes of cooling or less.

Transfer cooled logs onto the chopping board and use a large, sharp serrated knife to slice them at an angle. Each slice should be about 2 cm wide, but you don't have to be super-precise. Place the biscotti back on a cookie sheet/ baking tray, cut side down and bake at lower temperature for 6 more minutes on each side.

Storing and freezing instructions

What's really great about these lemon pistachio biscotti is that they last for a really long time! When stored in the airtight container, they will last for good 2-3 weeks.

You can also freeze biscotti for up to 3 months, in couple of different ways:

1. You can freeze half-done biscotti. After their first bake, allow them to cool, then transfer to the freezer-friendly container. Bake them for the second time whenever you are ready.
2. Freeze fully-baked biscotti, in the freezer-friendly container. To thaw, remove them from their container and allow them to sit at room temperature until they are back to life.

They may loose some of their crunchy texture after thawing them, but you can simply re-heat them in the oven to get them crispy again. Here's a link to a really detailed instructions on freezing the biscotti.

Is biscotti supposed to be hard?

Yes! They're meant to be hard and crumbly, it is what makes them perfect for dunking in hot beverages. If you enjoy lemon flavour, but prefer softer cookies, check out these Lemon Cookies from Boston Girl Bakes blog. Or try making these Italian Amaretti Cookies, which are soft and chewy in the middle, with crisp shell on the outside. These Pignoli Cookies are also a fantastic alternative.

What else can I mix into the dough?

Almost anything! You can use any nuts or dried fruit, chocolate chips or different spices to create different variations of this recipe. Comes December, and these would make perfect edible gifts for friends and family (my Cranberry and Amaretto Biscotti is a perfect, festive recipe!).

Can I make this recipe gluten-free?

Yes you can. Simply swap the plain flour for gluten-free flour, and make sure you use gluten-free baking powder.
