Gluten Free Sourdough Starter Recipe (2024)

FAQs

How much should I feed my gluten free sourdough starter? ›

You'll want to use whole grain gluten-free flour – something like brown rice flour, buckwheat flour, sorghum flour, or millet flour. Do NOT use a gluten-free flour blend, which can contain starches, gums, and other additives that you don't want in your starter.

Sometime between days 5 and 10, you'll notice that within several hours after feeding the starter will have grown in size to between 2 1/4 and 2 3/4 cups. At this point it's ready to use in your recipe.

If your starter is struggling to double, place it somewhere warm, like inside a turned off oven with a light on. You can also try feeding twice a day to nudge the starter along. Once the starter has doubled in size, is bubbly, and has a sweet-sour aroma, it's ready to use in your gluten free sourdough bread recipe.

The most common feeding ratio is 1:1:1 (sourdough starter: flour: water). This is also known as a 100% hydration starter. For example, let's say you have 40 g of sourdough starter in a jar. To feed it, you'll add 40 g of flour + 40 g of water.

This is usually described by referring to ratios. So, a sourdough feeding ratio is the relative amount (referring to weight) of old sourdough compared to fresh flour and water. Typical feeding ratios are 1:2:2 or 1:3:3 (old sourdough: fresh flour: water). However, even extreme ratios like 1:50:50 would still work.

You can perform a float test to check if your starter is ready. Take a small spoonful of the starter and drop it into a glass of water. If it floats, it indicates that the starter is sufficiently active and ready for use.

If you plan on baking gluten free sourdough often, just keep your starter on the counter and feed it at least once a day. If you don't plan on baking as often, you can store your starter in the refrigerator and feed it once a week.

Overproofing is common, but will not harm the final bread. If the dough has risen too much, stir it down in the pan and let it rise for another 20 minutes, then bake as directed. Always cool bread before serving.

Your sourdough starter can be runny because:

You're not weighing your ingredients accurately or measuring by volume. It's too warm in your kitchen. The flour you're using needs less hydration. You're not feeding your starter regularly enough.

Why does my gluten free sourdough starter keep molding? ›

Young sourdough starters have not had enough time to develop good bacteria necessary to prevent mold. A strong presence of beneficial bacteria wards off pathogenic bacterias, or those which cause disease.

The simple reason is that gluten free bread takes much longer than a regular loaf to bake and therefore a sticky crumb is generally the result of under baking (there could be other reasons but this is the first place to start troubleshooting).

Premature discarding and overfeeding will weaken your starter and elongate the process. Don't discard and re-feed a weak starter before it shows increasing bubble activity or height from the previous feeding. If you don't see more bubbles or a faster rise each day, skip a feeding, and give it more time.

If you're feeding a sourdough starter by weight, the ratio of starter to water to flour is 1:1:1. So If you're using 50 grams of starter, add 50 grams of water and 50 grams of flour. If you want to feed a sourdough starter by volume, the ratio of starter to flower to water is 1:1:1.75.

Once it's ripe, remove the amount you need for the recipe (I almost always use between 100-200 grams) and then save 20 grams, feeding it with 20 grams water and flour. You're back to having 60 grams of starter to keep for next time with enough to bake your bread now.

There is no single best ratio, but I've found a ratio of 1:5:5 fed twice daily at 12-hour intervals to produce a sourdough starter that's strong and healthy. This ratio corresponds to 20% ripe starter carryover, 100% water, and 100% flour (a mix of whole grain rye and white flour) at each feeding.
