About this product

Sourdough Mumma Gluten Free Organic Sourdough Starter 20g is a dehydrated live culture for beginning a gluten-free sourdough routine at home. Known as ‘Oscar’, the starter is made from an organic rice flour blend and filtered water, then dehydrated for convenient storage and activation. It is designed for use with Sourdough Mumma Gluten Free Feed My Starter Mix and can be prepared for gluten-free sourdough bread, focaccia and other suitable recipes.

To activate the starter, you will need a clean 1.5 litre jar, filtered water, kitchen scales, a fork and the matching gluten-free feed mix. The pack provides staged feeding instructions, with time allowed between feeds for the culture to become bubbly and active. Temperature affects fermentation, so activation can take longer in cooler conditions. Follow the current packet directions and the brand’s step-by-step guidance carefully rather than relying on a fixed activation time.

Once active, remove the amount of starter required for your recipe and keep the remainder refrigerated in a well-sealed jar. Regular feeding helps maintain the culture for future baking. The manufacturer recommends keeping the starter on the bench while feeding and activating it, then returning it to the refrigerator when it is not in use. This creates a useful pathway from the initial starter to repeat baking with the feed, bread and focaccia mixes. Kitchen scales help make each feed more consistent.

The 20g pack is gluten free, vegan and made without wheat, eggs, nuts, soy, added sugar, corn, gums, genetically modified ingredients or instant yeast according to the current brand information. As ingredients, processes and instructions can change, always read the packet supplied before activation or consumption. Store the unopened dehydrated starter in a cool, dry place. After activation, follow the packet’s refrigeration and feeding instructions and discard the culture if mould or other spoilage develops.

Ingredients

Directions for use

Warnings & suitability

Follow the current packet directions carefully. Fermentation time varies with temperature. Use clean equipment and discard the culture if mould or other spoilage develops. Always check the supplied pack for current ingredient and dietary information.
