Shortbread That Doesn't Taste Like a Tin
Picking and working your butter
Okay. New module, and I want to start with a confession. Shortbread is three ingredients, sometimes four if you count salt, and it is somehow the cookie people mess up the most in this class. Not because it's hard. Because it's simple, and simple recipes have nowhere to hide. Bad butter shows up. Overworked dough shows up. There's no molasses or spice to cover for you here. It's just flour, sugar, and butter, standing there naked, telling on you.
So let's talk about the butter first, because that's most of the problem.
What kind of butter to buy
Get real butter, not a spread, not anything that says "light" or "whipped" on the label. Whipped butter has air beaten into it and that changes how it behaves in dough. You want plain, standard butter, and honestly the brand matters less than people think. I'm not precious about brand names for this one. What I am precious about is fat content, and European-style butters (usually 82-84% fat instead of the standard 80%) make a noticeably better shortbread. Less water, more fat, cleaner crumb. If you want to splurge on one thing this module, splurge there. If your budget says no, a regular stick of butter from wherever you already shop will still make a good cookie. Don't let anyone tell you otherwise.
Salted or unsalted, your call. I use unsalted and add my own salt so I control it, but I know people who've used salted their whole lives and their shortbread is fine.
Room temperature means room temperature
Here's where people get it wrong. "Softened butter" does not mean butter you microwaved for twenty seconds because you forgot to take it out. Microwaved butter goes soft on the outside and stays cold in the middle, or worse, starts to melt in spots. Melted butter and softened butter behave completely differently once they're in dough. Melted butter makes your shortbread spread and go greasy. Softened butter creams properly and holds its shape.
Real room temperature butter should give a little when you press it with a finger, but it shouldn't be shiny or soft-looking. If you press it and your finger goes in like it's clay, it's too warm. Put it back in the fridge for ten minutes.
Plan ahead here. Pull your butter out about an hour before you start, sitting on the counter, still wrapped. In a cold kitchen in December that might take longer, especially if your kitchen runs cool like a lot of houses up here do in winter. I've had butter take an hour and a half some days. Just don't rush it with heat.
Creaming: less than you think
Once your butter's soft, you're going to cream it with the sugar. This is the part where I watch people go too far. You want the butter and sugar to come together, look pale and a little fluffy, and that's it. Stop. You are not making a cake batter. You are not trying to whip air in for three straight minutes.
I feel like this is a texture thing people don't connect until they taste the result. Overcreamed shortbread bakes up cakey and a little too soft. Undercreamed and you get dense, but properly done, it should be sandy and short, which is the whole point of the name. Short means it breaks clean, not chewy, not cakey. About a minute and a half with a hand mixer on medium is usually right. With a stand mixer, even less.
Working the flour in
When you add your flour, mix it in on low speed or by hand, just until you don't see dry streaks. The second flour goes in, you're building gluten every second you keep mixing, and gluten is what makes shortbread tough instead of tender. This is the same rule as pie crust. Undermix flour, always. If it looks a little shaggy and not fully smooth, that's correct. It'll come together when you press it into the pan or roll it out.
Why I even teach this class
I want to tell you honestly, I almost didn't teach any of this. A while back Beverly from the ward talked me into doing a class at all, and I remember telling her, I feel like I'm not really qualified, I just bake at home. And she just said the grocery-store tins spoke for themselves. That was the whole conversation. She didn't argue with me, she just said that, and I didn't have a comeback, so here we are.
I bring that up here specifically because shortbread is the cookie that most reminds me of those tins. Everyone's had the version that tastes like cardboard with a butter rumor in it. That's usually not a bad recipe. That's usually bad butter handling, at one of the two steps I just walked through.
Before next time
Buy your butter and get it sitting out on the counter the night before or at least an hour ahead, and notice how long it actually takes to soften in your kitchen. That timing is going to matter a lot next lesson when we mix the dough for real.
