If there were a personality test for biscuits, it would look something like this: a map of the United States filled with pins, dusted with flour and streaked with butter, with a big honking question mark superimposed over the whole thing.

Because there is no one perfect biscuit: There’s just the biscuit that’s perfect for you.

Unlike, say, a macaron or even a bagel, biscuits lend themselves particularly well to tweaks to suit your taste. Sure, there’s chemistry and intertwining causes and effects at work, and we’ll get to all that, but a little well-thought-out experimentation is welcome.

“When you go to make biscuits, I think you need to know what you want,” says Martin Philip, head baker at King Arthur Flour. His history is so intertwined with the baked good that the first recipe in his cookbook, “Breaking Bread: A Baker’s Journey Home in 75 Recipes,” is for biscuits.

So what do you want? The biscuit matrix covers fluffy and tender to flaky and sturdy enough for a sandwich. You might want them tall, maybe a little tangy or decadently buttery. You could go the drop-biscuit route, bust out the rolling pin or practice your folding skills.

Here’s everything you need to consider.

For flaky biscuits, use your fingers to flatten the butter into “leaves” that are still visible in the dough.

Flour

Cookbook author and Southern food ambassador Nathalie Dupree swears by White Lily Flour so much that she brought her own bag to our Food Lab.

Cooks like Dupree treasure self-rising White Lily (it has salt and leavening in it already) for its fine-milled texture and low-protein content (8 to 10 percent), which lead to especially tender biscuits. Flour with lower protein forms less gluten when it comes into contact with liquid in the form of the water in butter, or your dairy of choice. More protein means more gluten, which means a chewier texture.

Ayeshah Abuelhiga advocates a middle-of-the-road approach with all-purpose flour (10 to 12 percent protein). The founder and CEO of Washington’s Mason Dixie Biscuit says her team started testing recipes with pastry and cake flour, which have even less protein than White Lily, but the crew found the results too inconsistent and caky, and too weak for a sandwich.

Bread flour’s high protein content makes it a no-go for biscuits.

Liquid

This is where the other part of the gluten equation comes into play; just like flour, liquid will help determine tenderness.

If you like biscuits with layers that practically pull apart themselves, chill the dough in between folds.

Up to a certain extent, more water means more gluten. If you’re working with all-purpose flour, use less liquid. (A wetter dough is more suited to fluffy drop biscuits, which we’ll get to later.)

When selecting and working with your liquid, keep these tips in mind:

* Rise. Buttermilk’s tangy flavor and thick texture are enough to recommend it, but its acidity also gives the baking soda and/or powder something to react with, Philip says. A more vigorous reaction means a higher rise.

* Richness. While developing a scone recipe, Philip says he had a “light bulb” moment. Using buttermilk gave him the flavor he wanted but not the texture. He swapped the buttermilk for half-and-half, and the additional fat resulted in an especially tender scone. You’ll get similar results in a biscuit, especially if you step up to cream.

* The right mix. For tender results, use a wide bowl and stir the liquid in until it’s just incorporated. You may need to dial back the liquid if you’re in a warm, humid environment or add a bit when it’s cool or dry.

Fat

A buttery biscuit owes its melt-in-your mouth texture to fat, which tenderizes the dough by interfering with the formation of gluten.

“What I hate is a doughy biscuit that doesn’t have enough butter in it,” says Tom Douglas, the chef-restaurateur behind Seattle’s Serious Biscuits. (The biscuit recipe in “The Dahlia Bakery Cookbook,” which Douglas co-wrote with his company’s quality-control manager, Shelley Lance, calls for three sticks of butter for a 20-biscuit batch.)

Philip also prefers the flavor and texture that butter imparts. Shortening has no water, which is key for producing the steam that helps lift the biscuits. Butter, by contrast, has almost 20 percent water. Shortening “also really has no flavor,” he says.

Lard, like shortening, is 100 percent fat. Erika Council, a food writer who runs the Bomb Biscuits pop-up in Atlanta, says her best biscuits are made with lard, “hands down.” They’re especially tender in the middle while still managing to hold together. The key, however, is finding good lard, which Council can do because she sources hers from her best friend’s barbecue spot.

If you’re struggling to get a tender biscuit, the answer is almost always more fat and less moisture. And don’t forget that fat can come from your liquid: The cream biscuit recipe below, from Cook’s Illustrated, is one example of how well it can work on its own.

For a last touch of richness and flavor, consider brushing melted butter onto your biscuits. Brushing before baking gave me a darker color and crisper texture on top.

Temperature

As with all baking, management of temperature is key. Right from the beginning.

* Cool ingredients. If the butter starts to melt as you’re mixing the dough, water moves into the flour, forming gluten. The goal is to keep the butter as cold as possible before the dough goes into the oven, so try refrigerating your dry ingredients and butter. When the butter melts in the oven, it gives off steam that creates flake and lift.

* Chill the dough. Chef Marjorie Meek-Bradley of Washington, D.C. tavern St. Anselm has earned a cult following for her tall, flaky biscuits. She refrigerates her dough – which is made with frozen, grated butter – several times, between the folds she executes for guaranteed layers. I tried it with 20- to 30-minute rests in the fridge, which gave me dramatic layers.

* Hot oven. With a relatively short bake time, a hot oven gives you an initial blast that activates the leavener (double-acting baking powder starts working when exposed to liquid and heat) and quickly melts the butter to create steam. For Philip, a hot oven is 425 degrees. For the Cook’s Illustrated cream biscuit recipe, it’s 450. For Douglas’s uberbuttery version, it’s 475.

* Even out the heat. Avoid scorching the bottoms of the biscuits by baking on a lined sheet in the upper third of the oven. Knowing whether your oven has hot or cool spots is helpful, but you can make up for them by rotating the sheet from front to back during baking. And use the convection feature if you have one. The fan circulates hot air, helping you achieve an even bake.

When brushed on right after baking, melted butter soaks into the biscuit for an especially rich texture.

* Know when the biscuits are done. Look at the color. Philip wants to see a golden top, and signs of browning on the bottom and sides of the biscuits. Browning means better flavor. “You need to have the kiss of the oven,” he says.

Technique and tips

How you form and arrange your biscuits has as much impact as what you put in them.

* Flaky or fluffy? If your goal is flaky, then folding your dough, as you would in puff pastry, is the way to go. If you prefer a fluffy, craggy biscuit that you can tear apart and treat more like a dinner roll, try a drop biscuit.

* Building height. Baking the biscuits closer together can make them taller, because as they share heat, it enhances the steam effect. When I tried this with the biscuits a finger-width apart, I got a more dramatic rise and more consistent color on top than with batches with more space between them. The tradeoff: less browning on the edges and a texture that’s more steamed than flaky.

* Clean cuts. The sharp edges of your chef’s knife, bench scraper or biscuit cutter and a straight-down (no twisting!) cutting motion contribute to tall biscuits.

No matter how you get there, everyone agrees: Biscuits are best eaten warm out of the oven.

“Biscuits should be a daily thing,” says Philip. “It’s that thing that should be made at the minute by the person there. You’re capturing a moment with a biscuit.”

FLAKY BUTTER BISCUITS

Depending on the temperature and humidity of your kitchen, you may need to use more or less buttermilk.

Makes 8-12 servings

8 tablespoons (1 stick) cold unsalted butter

Scant 3 cups flour, plus more for the work surface

1 teaspoon table or fine sea salt

1 teaspoon baking powder

1/4 teaspoon baking soda

1 cup plus 1 tablespoon regular or low-fat buttermilk

2 tablespoons salted or unsalted butter, melted, for optional brushing

Cut the cold butter into 1/8-inch-thick slices; refrigerate until you’re ready to make the dough. Whisk together the flour, salt, baking powder and baking soda in a mixing bowl, and refrigerate that as well. Position a rack in the upper third of the oven; preheat to 425 degrees. Lightly grease a rimmed baking sheet, or line it with parchment paper or a silicone liner.

Add the cold butter pieces to the chilled dry ingredients, tossing them until they are evenly coated. Press the butter pieces between your thumbs and forefingers into small flat pieces, or “leaves.” Add the buttermilk, as needed, and mix gently until just combined. The dough should be barely cohesive; don’t worry if there are dry bits, because they will be incorporated as you pat and fold the dough.

Lightly flour your work surface. Transfer the dough there, patting it into a 3/4-inch-thick rectangle. Fold the dough in thirds as you would a letter, bringing one-third in over the middle third, followed by the final third over the other two. Gently roll or pat the dough into another rectangle. Repeat this fold-and-roll process once more if the dough isn’t cohesive or if you want to create more layers.

Lightly flour the top of the dough. Use the 2-inch cutter to create 10 to 12 rounds of dough, being careful to cut straight down and not twist the cutter (to ensure the biscuits get the best rise). You can reroll the dough once, though you might not get the same rise. Or use the bench scraper or a sharp chef’s knife to square the sides and edges of the dough rectangle, then cut eight to 10 squares or rectangles. Place the biscuits on the baking sheet, spacing them about 2 inches apart.

Bake (upper rack) for 16 to 18 minutes, rotating the pan from front to back after 14 minutes, until the biscuits are golden.

If you wish to brush the biscuit tops with melted butter, do so as soon as they come out of the oven. Serve warm, or at room temperature.

DROP CREAM BISCUITS

The biscuits can be stored in zip-top bag at room temperature for up to 24 hours. Reheat them in a 300-degree oven for 10 minutes.

Makes 10-11 servings

3 cups flour

1 tablespoon plus 1 teaspoon sugar

1 tablespoon baking powder

1/4 teaspoon baking soda

11/4 teaspoons salt (table)

2 cups heavy cream

2 tablespoons salted or unsalted butter, melted, for optional brushing

Position a rack in the upper third of the oven; preheat to 450 degrees. Line a rimmed baking sheet with parchment paper or a silicone liner. Whisk together the flour, sugar, baking powder, baking soda and salt in a mixing bowl.

Microwave the cream in a microwave-safe container on HIGH for 60 to 90 seconds, until just warmed to body temperature (95 to 100 degrees), stirring halfway through. Stir the warm cream into the flour mixture to form a soft, uniform dough.

Grease a 1/3-cup dry measuring cup with cooking oil spray. Use it to drop 10 or 11 level scoops of batter 2 inches apart on the baking sheet; the biscuit portions should measure about 21/2 inches wide and 11/4 inches high. Regrease the measuring cup after every three or four scoops. If the portions are misshapen, use your fingertips to gently reshape the dough into level cylinders.

Bake (upper rack) for 10 to 12 minutes, until the tops are light golden brown, rotating the pan from front to back halfway through.

Brush the hot biscuits with melted butter, if desired. Serve warm.
