Getting Scones Right With Plain Flour
Plain flour works fine for scones. You don't need self-raising if you know what you're doing. I've made hundreds of batches over the years and plain flour actually gives you more control because you're adding the raising agent yourself rather than hoping the pre-mixed bicarb in self-raising is still fresh. Start with 225g plain flour, a teaspoon and a half of baking powder, a pinch of salt, and about 80g of cold butter. Cut the butter into cubes and rub it into the flour until it looks like breadcrumbs. Mix in 110ml of milk (full fat is worth the bother) and a couple of egg yolks if you want richer scones. Bring it together gently, pat it out to about 2cm thick, cut into rounds, and bake at 220°C for 12 to 15 minutes. The whole thing takes maybe 20 minutes from start to finish. That's genuinely faster than most people think it will be. The trick is keeping everything cold. Your hands, your bowl, the butter, the milk — if anything warms up too much the fat melts into the flour and your scones turn dense. I keep a tray in the freezer and drop my knife through there between cuts. It sounds like overkill but it makes a noticeable difference.
What Actually Happens When You Mix
Baking powder is your chemical leavening agent here. It releases carbon dioxide when it hits moisture and heat. That gas gets trapped in the gluten network and creates those air pockets. Too much handling and you develop the gluten too far, which means tough scones. Not enough mixing and they don't hold together at all. You're looking for a shaggy dough that comes together without you kneading it like bread. One thing nobody tells you: the age of your baking powder matters more than most people realise. I once used a tin that had been sitting in the back of the cupboard for two years and got rock-hard biscuits instead of scones. Test it by dropping a teaspoon into hot water. If it fizzes aggressively, you're good. If it barely murmurs, bin it and buy a new tin.
The Problem With Rolling
Don't roll your scone dough out on a surface. Pat it out directly on the baking tray or a lightly floured board. Rolling adds flour and you have to work the dough more to incorporate it, which toughens everything. Patting is faster and gentler. I also found through experience that cutting straight down with a round cutter rather than twisting is important. Twisting seals the edges and prevents the scone from rising properly. It sounds minor but I've had scones that rose to about 4cm and others stuck at 2cm because I was twisting the cutter out of habit from making pastry.

When Plain Flour Won't Work For You
If you're making scones for people who need gluten-free options, plain wheat flour obviously isn't going to work. There are blends available now that substitute 1:1 but the texture will be different regardless of which brand you use. Also if you're trying to make these low fat, reducing the butter below about 60g for 225g of flour tends to produce something closer to a bread roll than a scone. The fat percentage matters more than you'd expect. Storage is another limitation. Fresh scones are best eaten within a couple of hours of baking. They're okay the next day but they're never as good. You can freeze them uncooked though — shape them, put them on a tray in the freezer, then transfer to a bag. Bake from frozen and add about three minutes to the cooking time.
Why Your Scones Might Be Going Wrong
If they're flat, your baking powder is stale or your oven wasn't hot enough. If they're tough, you handled the dough too much. If they're dry inside, you baked them too long or the milk quantity was wrong for your flour. Different brands absorb liquid differently and I've had to add another tablespoon of milk when using a certain type of stoneground plain flour that seemed to drink everything. There's no single perfect recipe because flour varies. But the ratios above are a solid starting point and you'll figure out the adjustments after your second or third batch. Most people just need to stop overworking the dough and make sure the oven is properly preheated before putting the tray in.
