Banneton Care: How to Use, Clean, and Store Your Proofing Baskets

Bannetons are some of the most useful sourdough tools — and the most often misused. New bakers stick dough to them, treat them roughly, or clean them in ways that ruin them. Here's how to use, care for, and extend the life of your proofing baskets.

What a banneton is

A round or oval basket made of woven cane or rattan, used to hold the shape of a fermenting loaf. The spiral pattern from the basket transfers to the dough surface and gives sourdough its characteristic look.

Most home bakers use 8–9 inch round (boule) and 10×6 inch oval (batard) bannetons.

Lined vs. unlined

Lined (linen liner inside the basket)

• Less sticky, easier for beginners
• Smooth surface on the bread (no spiral pattern)
• Easier to clean

Unlined (bare cane)

• Spiral pattern on the bread (the classic look)
• Wicks moisture away from the dough surface (better skin)
• Harder to clean, more prone to sticking until seasoned

Most bakers prefer unlined for the look and skin development.

Seasoning a new banneton

A new banneton needs to be seasoned (built up with flour) before it stops sticking.

First use

1. Lightly mist with water
2. Heavily dust with rice flour or a 50/50 mix of bread flour and rice flour
3. Use it for a bake — dough will likely stick a little

After each use

1. Don't wash
2. Tap out excess flour
3. Dust with more flour for next bake

After 3–5 bakes, the basket has a thin layer of dried flour worked into the cane. This is the seasoning. Dough stops sticking.

Why rice flour

Rice flour doesn't absorb water the way wheat flour does. It stays on the surface as a barrier between the dough and the basket. Wheat flour gets absorbed into the dough and stops working.

Use 100% rice flour for the dustiest, least sticky bannetons. Or 50/50 rice and wheat flour for a compromise.

Common mistakes with bannetons

Washing with soap — destroys seasoning. Don't.

Soaking in water — warps the cane and ruins the basket.

Storing damp — invites mold. Always dry completely.

Heavy flour on top of dough — falls into the cane, gets sticky later.

Putting in dishwasher — destroys it permanently.

How to clean a banneton

Light cleaning (after every bake):

• Tap out excess flour
• Brush with a stiff bristle brush

Deeper cleaning (every 10–20 bakes):

• Dry brush thoroughly
• Tap upside-down on the counter to release stuck flour
• Place in a 250°F oven for 30 minutes to dry out and kill any moisture-loving microbes

Heavy cleaning (when really dirty or moldy):

• Brush thoroughly
• Wipe with a slightly damp cloth (water only, no soap)
• Dry in a 250°F oven for 1 hour
• Re-season before next use

How to store

• Open air is best
• A pantry shelf, hanging on a hook, or upside-down on a wire rack
• Don't seal in plastic (traps moisture)
• Don't store in damp basements

How long they last

A well-cared-for banneton lasts 5–10 years of regular use. They're durable.

Signs it's time to replace:

• Cane is splintering
• Mold that won't go away after cleaning
• Severe warping or cracking
• Bottom is wearing thin

What to do if dough sticks

If you've turned out the dough and it's stuck in places:

1. Don't try to scrape it out hot
2. Let the basket cool completely
3. Brush out the dried bits
4. Re-season more aggressively next time

For especially troublesome doughs, line the basket with a tea towel for the next bake.

The basket size question

For a 1kg dough boule:

• 9-inch round (23cm) is standard
• Holds 700–900g of dough

For a 1kg batard:

• 10×6 inch oval (25×15cm) is standard
• Holds 800g–1kg

Buying a banneton too big means the dough flattens. Too small means it bulges over. Match basket to typical dough weight.

DIY banneton alternatives

Don't have a banneton? Use:

• A bowl lined with a heavily flour-dusted tea towel
• A wicker bowl from a thrift store, lined with cloth
• A colander lined with a tea towel

These work fine but won't give the spiral pattern.

The investment vs. the return

A good banneton costs $15–25. It will produce hundreds of loaves over its life. Per loaf, that's a few cents.

For something this useful, it's one of the best small investments in a sourdough kitchen.

A note on shape

Round (boule) bannetons make boules. Oval (batard) bannetons make batards.

If you can only afford one, get a round one. Round loaves are more versatile, easier to bake in a Dutch oven, and fit standard recipes more easily.

If you bake regularly, owning both sizes lets you switch between shapes for variety.
