Scoring Sourdough: Why Your Cuts Disappear and How to Get a Real Ear

Scoring is where sourdough often goes sideways. In videos, a baker drags a blade across the dough in one clean motion, and a gorgeous ear peels open in the oven. At home, the score line seals back shut during baking as if it had never been cut at all. The problem is usually not your hand, it is everything else around the cut.

Scoring is not just decoration. It is a functional step that controls where your loaf expands in the oven. Without a score, the dough finds its own weak point and bursts open unpredictably, usually at the seam. A good score directs that expansion exactly where you want it, creating a controlled opening that becomes the ear.

Why Your Score Lines Disappear

If your cuts are vanishing in the oven, one of these three things is almost certainly happening:

1. The Dough Is Over-Proofed

An over-proofed loaf has exhausted most of its rising power before it hits the oven. When there is very little oven spring left, there is nothing to push the score open. The cut just sits there and heals shut as the crust forms. This is the number one reason for disappearing scores.

2. The Cut Is Not Deep Enough

A timid, shallow score gives the crust very little to work with. You need to cut about a quarter to a half inch deep, enough to create a real flap of dough that can lift and curl as steam hits it. Most beginners barely scratch the surface because they are afraid of deflating the dough. Go deeper than you think you need to.

3. Not Enough Steam

Steam is what keeps the crust pliable during the first 15 to 20 minutes of baking. Without it, the crust sets hard almost immediately, locking the score shut before the dough has a chance to expand. If you are not using a Dutch oven (which traps its own steam), your scoring results will always be inconsistent.

The Angle That Creates an Ear

This is the detail that changes everything. Most people hold the blade straight up and down, perpendicular to the dough surface, and make a vertical cut straight into the loaf. That creates a simple split, fine for some bread, but it will not give you an ear.

Think of it like peeling a sticker off a surface rather than stabbing into it. The shallower the angle of the blade, the more dramatic the ear. A perfectly vertical cut gives you a canyon. An angled cut gives you a curl.

Cold Dough Scores Better

If you are cold retarding your dough overnight in the fridge, and I strongly recommend you do, you already have a massive advantage for scoring. Cold dough is firm. The surface is taut and set. When your blade touches it, it cuts cleanly without dragging or tearing.

Room-temperature dough, on the other hand, is soft and sticky. The blade tends to drag, creating ragged edges that heal together in the oven. If you absolutely must score warm dough, chill your blade in the freezer for a few minutes first. It helps, but it is not a substitute for cold dough.

Choosing Your Blade

A bread lame with a curved razor blade is the standard tool, and for good reason. The curve allows you to hold the blade at that low angle naturally. Straight blades work too, but you have to be more deliberate about your angle.

Sharp matters more than expensive. A fresh razor blade from a bread lame, a clean box cutter, or even a very sharp serrated knife will all work. What will not work is a dull blade, it drags through the surface instead of slicing, which tears the gluten and creates rough, uneven edges.

Replace the lame blade every 5 to 8 bakes. Once it starts dragging even slightly, it is time for a new one. Blades are cheap. Your time and dough are not.

Simple Patterns That Look Great

You do not need to be an artist to score beautiful bread. These three patterns cover most situations:

• Single slash: One long, angled cut slightly off-center across the top of a boule. This is the classic ear-producing score. Start about a third of the way from one side and cut in a gentle curve to the opposite third.
• Cross: Two cuts forming an X or a plus sign on top of a boule. Each cut should be about 3 to 4 inches long. This gives you four points of expansion and a symmetrical open.
• Three parallel lines: For batards and oval loaves. Three diagonal cuts spaced about an inch apart. Hold the blade at that same low angle for all three.

Scoring is one of those skills where a small adjustment produces a dramatic visible result. Angle the blade lower, cut a little deeper, make sure the dough is cold and properly proofed, and that ear you have been chasing will finally show up. It is one of the most satisfying moments in baking, and once it clicks, you will never forget it.
