Pour the sugar and yeast into the bowl of your stand mixer (or a large mixing bowl) then gently pour over the warm water. Set the bowl aside for 5 minutes without stirring it.: The air will fill with a faint yeasty fragrance and the surface may look slightly foamy, which signals activation. You will hear almost nothing, but visually a few bubbles at the edges are a green light. Avoid stirring too soon, since that can disrupt the initial enzymatic process. One common mistake is using water that is too hot, which kills yeast, so check that the water feels warm not hot to your wrist.
Place the 60 g of butter into the microwave and heat on full for 30 seconds or until just melted.: You will notice the butter liquefy quickly and release a nutty, dairy aroma. The melted salted butter should be warm not bubbling, which keeps its fat structure stable for mixing. Overheating can brown the butter and change flavor, so stop heating as soon as it is fully melted and allow it to cool slightly if it is very hot.
Add this to the yeast mixture then add the flour and salt.: As you fold in the melted salted butter , the mixture will look slack at first, then begin to form a shaggy mass once the plain flour is introduced. You will smell the combination of dough and butter, and the texture will move from sticky batter to something you can work with. A common error is adding all flour at once without ensuring even distribution of salt , so sprinkle the salt across the flour for balance.
Use your dough hook on a low speed, and combine the ingredients (or use a fork if doing it by hand).: The dough will start to pull away from the bowl as gluten develops, producing a slight clicking sound from the mixer. You will feel resistance increase as the dough becomes more elastic. Avoid running the mixer at high speed which can overwork the dough and warm it excessively; low and steady is the way to get even gluten formation.
Knead for 5-6 minutes. If the dough is really too sticky add an extra tablespoon of flour.: During this kneading window you will notice the dough become smoother and springy, with occasional tackiness that is normal. When pressed, it should slowly bounce back. A sticky mass that never firms up suggests more flour is needed, but be cautious adding too much which yields dense bread. Resist the temptation to shorten the knead time, as under-kneaded dough will not trap gas effectively.
Once it has been kneaded, remove the dough hook, cover the bowl with cling film and leave it to double in size. About an hour.: The bowl will fill as the yeast produces gas, and the dough surface may show small bubbles and a taut skin. The aroma will turn lightly fermented and pleasant. If it does not double, the room might be cold; move the bowl to a warmer spot for gentle proofing. Avoid punching it down prematurely, as that will waste the trapped gas needed for lift.
Once it has risen, divide the dough into 6 pieces and form them into batons.: You will feel the dough relax as you divide, and shaping will produce smooth, elongated logs. The texture should be soft and slightly springy under your hands. If the dough resists shaping, let it rest for a few minutes to relax the gluten. A common oversight is rolling too tightly which can squeeze out gas and lead to tighter crumb.
Line a baking tray with cooking paper and place the breadsticks on it. Cover them with a tea towel and leave them for an hour.: The second proof develops final volume, and the dough will puff and feel airy when touched. The surface may show tiny pinprick bubbles, which is a good sign. Avoid rough handling while transferring, since pressing can deflate the shapes and reduce oven spring.
Preheat oven to 200ºC.: You will hear the oven hum as it reaches temperature, and the interior should feel consistently hot when you open it. Preheating ensures immediate oven spring and correct crust formation. Do not slide the sticks in before the oven reaches the full temperature, as a cooler oven yields pale, undercooked crusts.
Take a very sharp knife and score the rolls on the diagonal (2 or 3 scores per stick).: The clean slice will reveal a pale interior and create decorative vents that guide expansion. A sharp blade makes precise, neat cuts, producing crisp edges that brown attractively. Dull knives drag and deform the dough, so sharpen or use a lame to avoid tearing the surface.
Bake in the middle of the oven for 15 minutes.: The sticks will change color, moving from pale to a golden brown with a gently crisping exterior. You will hear a faint crackle of the crust setting and smell deepened, toasty notes. Underbaking leaves doughy centers, while overbaking dries them out, so aim for a golden hue as your visual cue.
A minute before you remove the rolls from the oven place the 40 g of butter into the microwave to melt.: The butter should liquefy and send a warm, rich aroma across the kitchen, ready to be brushed on hot bread. Melting at the last minute ensures the butter is perfectly warm for soaking into the crust. Avoid overheating to the point of browning, as that alters flavor balance.
Remove the breadsticks from the oven and carefully brush each roll with the melted butter. It will look like you have far too much butter but just start on the first roll and brush it with butter, then move onto the next. By the time you have done all 6, it will have soaked into the first and you can repeat. Do this until all the butter has been used up. (don't forget the sides of your breadsticks).: The hot bread will hiss softly as the butter meets crust, releasing a glossy sheen and intensified butter aroma. Brushing while hot helps the fat soak in, creating a tender surface that keeps the sticks indulgent. An easy mistake is applying cold butter which will not absorb properly and leave clumps, so always use warmed salted butter .
Eat warm.: The best sensory payoff is immediate warmth, with a buttery aroma and a soft interior that yields satisfying chew. Serve right away to enjoy the contrast between glossy exterior and pillowy inside. Waiting too long cools the butter and slightly firms the crumb, so plan to enjoy them while they are freshly brushed.
