Australian-Style Lemon Myrtle Shortbread

This Australian-style lemon myrtle shortbread creams butter with native lemon myrtle for a tender, intensely citrus-scented cookie, ready in just over an hour including chill time. Lemon myrtle smells more lemony than lemon itself, which sounds impossible until you actually bake with it and your kitchen fills with a citrus aroma sharper than any zest could manage. Serve a few alongside our Korean-style citron tea for an afternoon of very serious citrus business.

Instructions

1

Cream the butter and powdered sugar together until light and fluffy, about 3 minutes. Beat in the ground lemon myrtle.

2

Whisk the flour, cornstarch, and salt together, then gradually mix into the butter mixture until a soft dough forms.

3

Shape the dough into a log about 2 inches in diameter, wrap in plastic, and chill for 30 minutes until firm.

4

Preheat the oven to 325°F (160°C). Slice the log into 1/4-inch rounds and place on a lined baking sheet, spaced apart.

5

Bake for 16-18 minutes until the edges are just barely golden. The centers should still look pale, shortbread shouldn't brown much.

6

Cool on the pan for 5 minutes, then transfer to a wire rack. Dust with a little extra sugar while still warm if you like.

Zesty Tip: Lemon myrtle is a native Australian ingredient with an intensely lemony, almost eucalyptus-like aroma, much stronger than lemon zest. If you can't find it, use lemon zest plus a pinch of dried thyme to approximate the herbal note, though the flavor won't be identical.

Questions people actually ask

What is lemon myrtle?

It's a native Australian plant with leaves that have an intensely lemony aroma, often considered even more fragrant than lemon zest. It's sold dried and ground in specialty spice shops and online.

Can I use lemon zest instead?

Yes, use about a tablespoon of fresh lemon zest plus a pinch of dried thyme for a similar herbal-citrus effect, though it won't be identical to true lemon myrtle.

Why shouldn't shortbread brown much?

Classic shortbread is meant to stay pale with just a hint of gold at the edges. Over-browning dries it out and makes it taste more like a regular butter cookie than a tender shortbread.

How long does this keep?

Stored in an airtight container, these keep well for up to 2 weeks at room temperature, and the dough log freezes well for up to 3 months unbaked.
