Sourdough Baking Tools: What a Canadian Beginner Actually Needs
Sourdough needs fewer tools than the starter-kit listings suggest. You can bake a good loaf with flour, water, salt, a jar, a bowl and a hot pot with a lid. The rest makes the process more repeatable, and in a Canadian kitchen that often means dealing with the cold: from November to March many homes sit at 18–20 °C, and a starter that doubled in five hours in August can take ten. This guide sorts the essentials from the nice-to-haves and compares the tools we stock.
The minimum kit
- A digital scale that reads in 1 g steps. Sourdough recipes are written as ratios of flour, water and salt by weight. Cups are too inconsistent for flour, which can vary by 20 g or more per cup depending on how you fill it.
- A wide-mouth glass jar of about 1 L. Wide enough to stir and scrape, clear enough to see the bubbles, and big enough that the starter can double without escaping.
- A heavy lidded pot that is oven-safe to at least 250 °C (480 °F). The lid traps steam for the first 20 minutes so the loaf can rise before the crust sets. An enamelled or bare cast iron Dutch oven of 4.5–6 qt (4.3–5.7 L) suits a standard 900 g loaf.
- A razor blade or lame for scoring, so the loaf opens where you choose instead of bursting at the side.
With those four you can bake. A banneton, a bench scraper and a proofing mat are worth adding once you are baking every week.

Bannetons: rattan, cane, cotton rope or silicone?
Natural rattan or cane baskets wick a little moisture from the dough's surface, which helps the crust and leaves the familiar flour spiral. Dust them with rice flour, which sticks less than wheat flour. Cotton rope baskets behave similarly and are easier to clean. Silicone bannetons fold flat and go in the dishwasher, but they do not absorb moisture, so the dough can stick unless you use a liner. Match the basket to your pot: a 23 cm (9 in) round basket suits a 4.5–6 qt round Dutch oven, and a 25 cm (10 in) oval suits an oval pot or a loaf-shaped bread oven.
Sourdough in a Canadian winter
Temperature drives fermentation more than anything else. Most starters peak in roughly 4–6 hours at 24–26 °C, but take noticeably longer at 19 °C. You have three practical options:
- Use warmer water when you feed the starter and mix the dough, aiming for a dough temperature of about 24–26 °C (75–79 °F). A probe thermometer makes this easy.
- Find a warm spot: the oven with only the light on, or the top of the fridge. Check the actual temperature with a thermometer first, because some ovens get too hot with the light on.
- Use a proofing mat or box with a thermostat, which removes the guesswork and works during an overnight bulk ferment.
Flour also matters. Canada Western Red Spring is the country's largest wheat class, and the Canadian Grain Commission describes it as known for high-protein flour with strong dough properties; its 2025 harvest report puts No. 1 CWRS protein at around 14%. For sourdough, check the protein per serving on the Nutrition Facts table and choose a bread flour or a strong all-purpose flour.
Baking in a Dutch oven safely
Most recipes preheat the pot to 230–260 °C (450–500 °F). Check the maximum oven temperature of your lid knob: some enamelled pots ship with phenolic knobs rated lower than the pot itself, and a stainless replacement knob fixes that. Use a parchment sling or a silicone bread sling to lower the dough in, and long oven mitts. Health Canada notes that ceramic and enamel cookware can be a concern if glazes contain lead or cadmium, and that products made outside Canada may not meet Canadian limits (Health Canada, safe use of cookware), so buy enamelled cookware from established brands.
Frequently asked questions
What is the best sourdough starter kit for a beginner?
A kit that includes a 1 L wide-mouth jar, a 9 or 10 in banneton, a lame and a scraper covers the essentials. Add a 1 g digital scale and a lidded pot oven-safe to 250 °C, which kits rarely include. Our Qalvyn kit and OZLOOK kit are two examples.
Do I need a Dutch oven for sourdough?
No, but it is the easiest way to get steam in a home oven. Without one, bake on a preheated baking steel or tray and pour boiling water into a pan on the lower rack for the first 15–20 minutes.
What size Dutch oven is best for sourdough?
For a standard loaf made with about 500 g of flour, a round pot of 4.5–6 qt (4.3–5.7 L) or an oval of about 5 qt works well. Larger pots work, but the loaf may spread more before it sets.
Why is my starter slow in winter?
Almost always temperature. Feed with water at about 27–30 °C, keep the jar somewhere around 24–26 °C, and give it a few days of regular feedings to recover its rhythm.
How should I store sourdough bread?
Cut side down on a board for the first day, then in a breathable linen or beeswax-lined bag or a bread box. Plastic bags keep it soft but make the crust leathery. Slice and freeze anything you will not eat within three days.
