The most common mistake is giving up on day 3-4. Your starter will smell awful (like acetone or vomit) around day 3 — this is normal. Bad bacteria die off and wild yeast takes over by day 5-7. Do not throw it out.
Just two ingredients: flour and water. That's it. Wild yeast and bacteria are already on your flour and in your kitchen air — you're just creating the right conditions for them to thrive.
Standard ratio is 1:1:1 (starter : flour : water) by weight. Once established, feed once daily at room temp, or once a week in the fridge.
Pro tip: Use a rubber band or tape mark on your jar to track rise and fall — it removes all guesswork about whether your starter is actually doubling. Whole wheat or rye flour for the first 2 weeks dramatically speeds up activation because they contain far more wild yeast than white flour. Once active, you can transition to all-purpose.
50g whole wheat — recipe ingredient.
50g room-temperature filtered — recipe ingredient.

Dry and liquid measuring set. Baking requires precision — guessing ruins results.
For sifting flour, straining sauces, removing lumps. Used in most baking recipes.
Large wood or plastic board. Get one big enough that food doesn't fall off while chopping.
Balloon whisk for eggs, cream, sauces. Essential for any recipe that says 'whisk until smooth'.
Heavy-duty aluminum sheet pan. The workhorse of any oven — cookies, roasting, pastry.
For spreading frosting, glazes, and cream layers evenly. The tool pastry chefs actually use.
Wire rack for cooling baked goods evenly. Prevents soggy bottoms from steam trapped underneath.
Nesting bowls for prep, mixing, whisking. Stainless steel won't stain or absorb odors.
Heat-resistant spatulas for scraping bowls, stirring sauces, folding batters.
Non-stick baking liner. Prevents sticking, easy cleanup. Buy a roll, not pre-cut sheets.
One good knife replaces a drawer of mediocre ones. Victorinox Fibrox is the pro budget pick.
For pastry, cookies, pie dough. French style (no handles) gives better control.
KitchenAid or equivalent. Hands-free mixing, kneading, whipping. A lifetime investment for serious baking.
Tri-ply stainless steel. For sauces, custards, reductions. The pan you'll use most.
'Tartine Bread' by Chad Robertson or 'The Perfect Loaf' by Maurizio Leo — both walk you through starter to finished loaf with photos. Invaluable for understanding the why behind each step.
Essential — sourdough is done by weight, not volume. Even a $10 scale works fine. Eyeballing flour and water ratios is the #1 reason starters fail.
Optional but powerful — even substituting 10-20% of your flour with rye dramatically speeds up a sluggish starter. The most yeast-rich flour available.
For ongoing maintenance once your starter is established. Unbleached is preferred — bleached flour may contain agents that inhibit yeast.
For scraping down the jar sides and thorough mixing — incorporating air when you stir speeds up fermentation.
Optional but useful — starter is very temperature sensitive. Below 18°C it gets sluggish, above 28°C it over-ferments. Knowing your kitchen temp removes a huge variable.
Essential — wide mouth makes stirring easy and lets you see bubble activity on the sides. Plastic works but glass lets you monitor progress better.
