That Entente recipe looks good - similar to ones I've made, though mine are definitely . . . how do I say this . . . less healthy.
I just use more butter, but these recipes are a dime a dozen and technique is far more important.
I go for flaky biscuits. Here's what mine look like:
They're always brushed with an egg wash before going in the oven, occasionally also with melted butter when removed.
So, some tips:
Flour - White Lily ain't what it used to be so don't get hung up looking for it. If you want your biscuits a little lighter, substitute some cake flour (because it has less protein) for some of the all purpose flour. I highly recommend using a kitchen scale, looking up the weights per cup of the flours you are using (assuming you're using a recipe that doesn't specify grams), and then going 3/4 unbleached all purpose flour and 1/4 cake flour. On the other hand, if you don't mind slightly denser biscuits, just use all purpose flour. . . . whatever you like.
Fat - Butter, butter and more butter (and unsalted). That's what gives you flavor. You want to use lard? Go ahead, but I would still use at least 80% butter (I'm always at 85% or more). The lard adds a little flakiness, and some porky flavor if you're not using leaf lard. And don't use crappy butter. Get the good stuff - Plugra, Kerrygold or some other European or European-style or local, small batch butter. These butters taste better and most critically have less water content. If you use the average grocery store butters in your pie crusts or biscuits, your biscuits/pie crusts will never be as great as they can be. I can always tell when biscuits/pie crusts have been made with ordinary grocery store butter . . . always.
Grated hard boiled egg yolk - I learned this trick from Bon Appetit some time back and have employed grated egg yolk since. So if you use the Entente recipe, take a couple of cold, hard boiled egg yolks and grate them (best to push through a sieve) into the flour before adding the butter. This adds protein and richness without making the biscuits any heavier. If you just added an uncooked egg yolk, the biscuits will be a little heavier.
Preparing the dough - 1) Cut your butter into 3/4 inch cubes and freeze for at least 30 minutes . . . this is a must; 2) mix the dry ingredients together (flour, powder, salt and if using, soda and sugar . . . fork, whisk, just to combine. 3) Then, mix the frozen butter into the flour mixture. Ideally, you'll have a Cuisinart or the like. Pulse until the butter is the size of peas (20 or so really quick pulses should get you there). 4) Place butter/flour mixture into a larger bowl, add buttermilk mixture (I say mixture because it may include cream or sour cream depending upon your recipe) and stir gently, just until mixture comes together. The more you work the dough, the tougher it will be (gluten formation, like making bread). 5) Refrigerate this massive lump for about 20 minutes. This allows biscuit dough to rest a bit and ensures that the butter stays cold (critical if you want flaky layers).
Rolling - The Entente recipe (and other good ones out there) mention a critical step.
Folds! Roll the dough out, maybe 3/4" thick. Then take the rolled dough and fold it over as if you were folding a letter to fit in an envelope. Roll out again, fold again, then roll again to 3/4" thickness. Ideally, refrigerate again for at least 10 minutes, though I'd recommend 20-30. It's all about keeping the butter cold.
Cutting - I like round biscuits, but I'll admit that the leftover scraps are a pain in the ass. Biscuits made from the scraps put back together just never looks as good. So an alternative is use a sharp knife/cleaver to form square biscuits. If using a biscuit cutter, dip in flour and do not twist . . . push straight down. This makes a huge difference in appearance. Same technique really if using a knife.
Putting in the oven - I like my biscuits to have a crisp bottom. To do this, preheat your pan with butter (clarified ideally but not a huge deal), and working very quickly, put all of your cut biscuits on the preheated pan.
There, go make biscuits!
