Guide to Sourdough Bread Using Cups, Ounces and Spoon Measurements

Sourdough bread has a magic all its own—the tangy flavor, the chewy texture, the golden crust that sings when you tap it. But if you’ve tried baking it before and ended up with flat loaves, dense middles, or starters that never seemed “alive,” you’re not alone.

Here’s the truth: sourdough isn’t just about skill—it’s about simplicity and patience. And for many bakers, the biggest barrier hasn’t been the process at all, but the measurements. Most recipes use grams and scales, leaving cup-and-ounce bakers feeling left out.

This guide is here to change that. Using cups and ounces, you can absolutely bake a beautiful, bakery-worthy loaf. Let’s walk through it together.

For Sourdough Starter

• Two straight-edged 16-ounce mason jars with lids. If you don't have mason jars, you can use the fancy type with a measurement guide that allows you to determine how your starter is growing.
• Something to stir the mixture in the jar; I use wooden chopsticks, but you can also use another narrow wooden or plastic stirring utensil that fits inside your jar.

For Baking Sourdough Bread

• Mixing bowl
• Mixing spoon
• Sharp knife
• Deep cast-iron Dutch oven baking pan
• Measuring cup
• Measuring spoon
• Optional Tools
• Banneton baskets for proving
• Lame for elaborate scoring bread for the artistic folks or a sharp knife for basic scoring.
• Bench scraper for portioning dough into parts and shaping a loaf
• A clean towel to cover the dough during the proving process.

Flour is the most essential ingredient. At least half of the flour should be whole grain, such as wheat or rye. Whole grain has more microorganisms, allowing for a much better start to your starter.

Salt of any type is acceptable; however, there is one vital thing you must know. Salt measurements vary depending on the type of salt you use. Coarse salts are measured differently from fine salts. 1 tsp of fine salt is the same as 1 1/4 tsp of coarse or kosher salt.

If you are someone who limits their salt intake, understanding is a crucial element to successful bread-making. You can restrict salt intake by 10% and still achieve a good loaf. I have included a reduced-sodium recipe below the original.

Water,  there is no need for fancy water. Tap water is fine if it is not heavily chlorinated, as it can prevent or reduce the growth of microorganisms. In such cases, filtered tap water is the best option or a good choice for those who want to err on the side of caution. Other than that, use room-temperature or lukewarm water.

The Starter - Using your 16 oz glass jar add

Time to Make Magic Happen

A sourdough starter is simply flour and water, left to ferment until it's full of wild yeast and healthy bacteria. You don't need fancy tools or metric scales—just a jar, a spoon, and patience. In about a week, you'll have a living, bubbling starter ready to bake with.

Ingredients

• ½ cup flour (2 oz) — all-purpose or whole wheat
• ¼ cup water (2 oz / 4 Tbsp) — room temperature, filtered if possible

Directions

Day 1

• In a clean glass jar or bowl, mix ½ cup of flour with ¼ cup of water until smooth.
• Scrape down the sides and loosely cover (a kitchen towel, coffee filter, or loose lid works).
• Let it sit at room temperature, away from direct sun, for 24 hours.

Day 2–6: Feeding Your Starter

• Each day, discard about half of the mixture (you can throw it away or save it for recipes like pancakes).
• Add another ½ cup of flour and ¼ cup of water. Stir until smooth, cover, and let it rest.
• By Day 3 or 4, you should start seeing bubbles and notice a tangy smell. This means the wild yeast is waking up!

Day 7: Ready to Bake

• When your starter doubles in size within 4–6 hours of feeding, smells pleasantly sour, and has a bubbly top, it's ready to use.
• To test, drop a spoonful in a glass of water. If it floats, your starter is strong and active.

Maintenance

• Keep your starter at room temperature if you bake often, feeding daily.
• If you bake once a week, store it in the fridge and feed it once before baking day to revive it.

👉 With just flour, water, and time, you've created the foundation for every sourdough loaf. And now, you can make it happen using simple cup and spoon measurements.

Step 1: Ingredients You'll Need

• 1 cup bubbly sourdough starter (use your starter when it is bubbly and has been fed within the last 4–8 hours)
• 1 ½ cups warm water (about room temperature, not hot)
• 4 cups bread flour (or all-purpose in a pinch)
• 2 teaspoons salt

That's it. Just four ingredients, measured in cups and spoons—the way most home cooks feel comfortable.

Step 2: Mix the Dough

1. In a large bowl, stir together the starter and water until the mixture becomes cloudy.
2. Add flour and salt. Mix to achieve a sticky dough.
3. Cover with a damp towel and let it rest for 30 minutes. (This rest is called "autolyse," and it helps your dough hydrate and relax before kneading.)

Step 3: Stretch and Fold

Instead of kneading for ages, sourdough loves a gentler approach:

• Every 30 minutes for the next 2 hours, uncover the dough and do a quick set of "stretch and folds."
• Grab the side of the dough furthest from you, pulling it upward to stretch, and then fold it toward you. Rotate the bowl and repeat this process four times.
• Cover the bowl between folds.

This strengthens the dough while keeping the process low-stress.

Step 4: Let It Rise

After your folds, cover the bowl and let the dough rise at room temperature for 6–8 hours. It should roughly double in size and look airy with bubbles.

Tip: If your house is cool, this may take longer—don't worry. Sourdough works on its own schedule.

Step 5: Shape and Second Rise

1. Turn the dough out onto a lightly floured surface.
2. Gently shape it into a round ball or an oval.
3. Place it seam-side up in a floured towel-lined bowl or proofing basket.
4. Cover and let it rise for another 2–3 hours, or place it in the fridge overnight for even better flavor.

Step 6: Bake Your Loaf

1. Preheat your oven to 450°F with a Dutch oven (or heavy-lidded pot) inside.
2. When hot, carefully place your dough inside seam-side down. Score the top with a sharp knife.
3. Cover with the lid and bake for 20minutes.
4. Remove the lid and bake for an additional 20–25 minutes, until the crust is deep golden and crackly.

Let your loaf cool at least an hour before slicing—this sets the crumb and makes cutting easier.

Blister Crust

One of the hallmarks of artisan sourdough is a thin, glossy crust covered in tiny blisters. These aren’t just beautiful—they add a shattering crunch and depth of flavor. The secret? Moisture.

Here’s how to achieve it at home:

1. Proof in the Fridge - After shaping your dough, let it rise overnight in the refrigerator. Cold fermentation helps break down starches in the dough, which encourages blistering during baking.

2. Preheat Your Oven and Dutch Oven - Heat your oven to 450°F with your Dutch oven (or heavy-lidded pot) inside for at least 30 minutes. You want everything piping hot.

3. Misting the Dough - Just before you place the dough into the hot Dutch oven, lightly mist the surface of the dough with clean water using a spray bottle. Alternatively, you can dip your hand in water and gently flick droplets onto the dough.

4. Bake Covered First -  Place the dough in the hot pot, cover with the lid, and bake for 20 minutes. The steam created inside will keep the crust moist, allowing blisters to form.

5. Finish Uncovered - Remove the lid and bake for an additional 20–25 minutes, until the crust is deep golden brown.

6. Optional Extra Mist - For an even more blistering effect, give a very light mist after removing the lid, then continue baking uncovered.

Ingredients

• 1 cup active sourdough starter (as described in the first recipe)
• 1 ½ cups warm water
• 4 cups bread flour (or all-purpose)
• 1 teaspoon salt(instead of 2)

Directions

1. Mix the Dough

• Stir the starter and water together until the mixture becomes cloudy.
• Add flour and salt. Mix until it forms a sticky dough.
• Cover with a damp towel and let rest for 30 minutes.

2. Stretch & Fold

• Every 30 minutes for 2 hours, perform 4 "stretch-and-folds" around the bowl.
• Cover again after each set.

3. Bulk Rise

• Let the dough rise at room temperature for 6–8 hours, until doubled and airy.

4. Shape & Proof

• Shape into a round or oval.
• Place in a floured towel-lined bowl or proofing basket.
• Cover and let rise 2–3 hours, or refrigerate overnight.

5. Bake

• Preheat oven to 450°F with a Dutch oven inside.
• Place dough in hot pot, seam-side down. Score the top.
• Bake for 20 minutes covered, then 20–25 minutes uncovered, until golden brown.
• Cool at least 1 hour before slicing.

Salt Content in This Loaf

• With 1 teaspoon salt (~6 g) in the dough, a baked loaf weighing about 700–800 g will contain ~0.7–0.8% salt by weight (half the standard amount).
• Per slice (12 slices), that's about 0.5 g salt (~200 mg sodium).

👉 The bread will still rise and brown well. The flavor will be milder, but the sour tang from your starter helps make up for it.

Congratulations Bread Maker
