How to Store or Freeze This Recipe
To store your gluten-free sourdough starter at room temperature, keep it in a glass jar with a loose-fitting lid. Feed it with equal parts gluten-free flour and water every 24 hours to keep it active and bubbly.
If you plan to take a break from baking, you can store the starter in the refrigerator. Place the jar in the fridge and feed it once a week with equal parts gluten-free flour and water. Make sure to let it come to room temperature and get bubbly before using it again.
For long-term storage, freezing is an excellent option. Transfer a portion of the starter to a clean, airtight container. Label it with the date and freeze it. When you're ready to use it, thaw it in the refrigerator overnight, then bring it to room temperature and feed it with equal parts gluten-free flour and water. Allow it to become bubbly and active before incorporating it into your recipes.
If you want to dry your starter for even longer storage, spread a thin layer of the active starter on a piece of parchment paper. Let it air dry completely, then break it into small pieces and store them in an airtight container. To reactivate, dissolve the dried pieces in water and feed with equal parts gluten-free flour and water, allowing it to become bubbly and active again.
Always use a clean, non-reactive container for storing your starter. Glass jars are ideal, as they do not react with the acidic environment of the sourdough starter.
When feeding your starter, use a wooden spoon or a non-metallic utensil to stir. Metal can react with the starter and affect its quality.
Keep an eye on the smell and appearance of your starter. A healthy starter should have a pleasant sour smell and be bubbly. If you notice any off smells, mold, or discoloration, discard the starter and start fresh.
If you find yourself with excess starter, don't discard it! Use it to make delicious pancakes, waffles, or even crackers. There are plenty of creative ways to incorporate leftover starter into your cooking.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place your gluten-free sourdough bread on a baking sheet and cover it with aluminum foil. Heat for about 10-15 minutes until it’s warm and slightly crispy on the outside.
For a quicker method, use a microwave. Wrap the sourdough bread in a damp paper towel and microwave on medium power for 30-60 seconds. This helps retain moisture and prevents the bread from becoming too hard.
If you have a toaster oven, set it to 350°F (175°C) and place the sourdough bread directly on the rack. Toast for about 5-7 minutes until it’s warm and has a nice crust.
For a stovetop method, heat a non-stick skillet over medium heat. Place the sourdough bread in the skillet and cover it with a lid. Heat for 2-3 minutes on each side until it’s warmed through and slightly crispy.
If you prefer a steam method, place a steaming rack in a pot with a small amount of water. Bring the water to a boil, then place the sourdough bread on the rack. Cover and steam for 5-7 minutes until it’s warm and soft.
For a more gourmet touch, brush the sourdough bread with a bit of olive oil or butter before reheating in the oven or toaster oven. This adds extra flavor and helps achieve a golden, crispy crust.
