What is brown butter?

The short version is what the name implies: butter that is browned.

Also known as the French beurre noisette (translates as hazelnut butter), it's butter (salted or unsalted) that is heated or cooked long enough for the water (yes, butter has water in it, sometimes a lot) to evaporate.

This leaves behind the solids that start to brown, turning golden or amber in color, and with a beautiful nutty aroma (hence the hazelnut reference).

Truly worth making, even though it's an extra step.

We have a whole post dedicated to it: how to make brown butter.

Tips to make brown butter shortbread

Shortcuts: make the brown butter ahead. It keeps for a month (at least) in an airtight container in the fridge and longer in the freezer.
Don't overwork the dough: for a tender shortbread, make sure the mixture is not kneaded or overmixed. This is not a pie crust that needs to come completely together. The mixture will be crumbly and come together as you pat it in the pan. A light touch is needed.

Brown butter goes from clear to brown in a second.

Much like caramel suddenly turns a very deep amber. So after melting the butter, it will bubble a lot and suddenly, the bubbles will subside. That's when it turns nutty and darker. It takes about 10 minutes.

So don't answer the phone, check your e-mail, or stuff like that. Stay by the stove. Please.

Kitchen notes

Organization: read the recipe first and ensure you have ingredients at the correct temperature, equipment, and enough workspace. This will make the process so much easier.
Baking time: keep in mind that all ovens and pans are different, even if they look the same or very similar. The baking time in my recipes is as accurate as it can be, but it might take you more or less time. You can use a thermometer (like the OXO oven thermometer) to check that your oven is at the right temperature. I recommend you keep track of how your oven works and what tiny details you might need to adjust.
Make ahead: shortbread can be kept in tins for a few weeks.
Toppings: you can drizzle them with melted semisweet chocolate or a citrus glaze.
