What Do I Need to Start Sourdough (2026) — 6 Things, About $57

Most sourdough starter guides spend the first three paragraphs explaining what a starter IS, then leave you with a vague "you'll also need a banneton and a lame" and a link to a $200 tool set on Amazon. The honest list is shorter than you think. Six things, about $53, and a real loaf is on the cooling rack by Sunday afternoon.

The short list

1. A kitchen scale that reads 0.1 g (~$19) — Etekcity Food Kitchen Scale, 0.1g with Bowl (11 lb) — the only tool on this list that actually matters. Sourdough recipes are written in baker's percentages, which means flour is always 100% and water, salt, and starter are fractions of that number. A 1-gram error on a 500-gram dough is a 0.2% swing, and most cheap kitchen scales read in 1-gram jumps, which means you're guessing within 5% on every measurement. The Etekcity here reads in 0.1-gram increments (1-gram is fine for water and salt, but a half-teaspoon of salt weighs 3 grams and your hand is not a scale), tares between ingredients so you can weigh flour right into the bowl, and ships with a small stainless bowl that doubles as a starter-feeding dish. The 11-pound capacity covers any loaf you'll bake this year. The 59,000+ reviews aren't an accident.
2. A big mixing bowl with a lid (~$12) — a 6-quart plastic or ceramic bowl, clear if you can find it. Bulk rise happens in this bowl, and the lid keeps the dough from drying a skin while it sits for four to six hours. A Cambro-style round container is the classic choice; any large salad bowl with a plate on top also works. The scale of the bowl matters more than the material: too small and the dough crawls up the sides, too big and you can't keep the wet dough from spreading.
3. A bench scraper (~$5) — a flat metal or plastic scraper, the kind bakers use to lift dough off the counter and divide portions. Sourdough is wet. It sticks to everything. The scraper is the difference between a clean handoff and a flour-dusted wrestling match. The metal ones last longer; the plastic ones are gentler on nonstick counters. Either path is correct.
4. A round or oval banneton (~$13) — a coiled cane proofing basket that holds the shaped dough during its final cold rise. The banneton does two things: it gives the dough structure as it proofs, leaving the spiral pattern on the bottom of the finished loaf, and it lets you flip the cold dough out into a hot Dutch oven without deflating it. A 9-inch round or 10-inch oval is the standard starter size. Skip the plastic "banneton" bowls with the spiral drawn on the bottom. The pattern from real cane looks better and the dough actually dries slightly into the weave, which makes the flip easier.
5. A lame or sharp blade (~$5) — a bread lame is a handle that holds a single-edge razor at a fixed angle for scoring the top of the loaf before baking. Scoring lets the bread expand where you want it to instead of bursting at the side. A fresh utility-knife blade in a pencil grip works the same way for less money. A kitchen knife is too dull; the score is the wrong shape and the dough drags behind the blade.
6. A kitchen timer (~$3) — the cheap plastic kind with a magnet on the back. Bulk rise, cold proof, and baking all run on time, and "I'll just check it in a few" is how a 14-hour bulk rise becomes a 22-hour over-fermented puddle. A $3 timer you can stick to the fridge is cheaper than the dough it saves.

Why the scale beats the rest

The other tools on this list are interchangeable. A bowl is a bowl, a scraper is a scraper, a kitchen timer is a kitchen timer. The scale is the one purchase that determines whether your bread comes out the same on the second try. Sourdough recipes are not forgiving the way cookie recipes are. A 5% hydration shift (50 grams of water on a 1000-gram dough) changes the texture from open-crumb to flat-pancake. Eyeballing "about a cup of water" works for pancakes, because pancakes don't care; sourdough is chemistry, and chemistry needs a scale.

What to skip

• A stand mixer, at least for the first month. Sourdough's stretch-and-fold technique works better by hand because you can feel when the gluten's developed. A mixer overworks the dough in a way you can't see until the loaf comes out flat. Add a mixer when you start baking two loaves a week, not before.
• A sourdough-specific "baking kit" with 14 tools. The kits bundle every item above, plus a silicone lid, a dough mat, a scoring pen, and a recipe card, for $80. Half the bundled tools are things you'd skip anyway. The scale alone is the most important piece, and the rest of the kit is stuff you own.
• A baking stone before you've baked five loaves. A Dutch oven does the same job a stone does, and you probably already have one. Stones make a marginal difference and the learning curve to using one right is steeper than the Dutch oven. Upgrade to a stone in month two if you're still baking.
• Specialty "sourdough flour." A strong bread flour like King Arthur or your store brand works fine. The flour snobbery is a year-two hobby. A reliable bread flour is a better starting place than the $14 bag of "artisan" flour from the fancy market.
• A proofing box with temperature control. The fridge is your proofing box. Cold retard overnight, shape in the morning, bake straight from the fridge. Boxes matter for bakers who bake daily in hot kitchens, not for someone on their first loaf.

The total

$19 + $12 + $5 + $13 + $5 + $3 = about $57, and street prices land between $50 and $65 depending on the bowl you already have and whether the banneton ships in a 2-pack. Add a $30 Dutch oven if you don't own one, and the whole setup lands around $87, which is the real cost of a hobby that produces actual bread. The starter, the flour, and the salt are consumables you refill as you go; the tools above are the one-time kit.
