Why Sourdough Discard Works So Well

Sourdough discard adds:

• Mild tanginess
• Moisture
• Depth of flavor

Since yeast is included in the dough, the discard contributes flavor without needing a long fermentation.

---

Choosing the Best Blueberries

Fresh blueberries work wonderfully during summer months.

Frozen blueberries are equally effective and available year-round.

No need to thaw frozen berries before cooking the filling.

---

Step 1: Activate the Yeast

In a large bowl combine:

• Warm milk
• Sugar
• Yeast

Allow to sit for 5–10 minutes.

The mixture should become foamy.

---

Step 2: Add Wet Ingredients

Mix in:

• Sourdough discard
• Egg
• Melted butter

Whisk until smooth.

---

Step 3: Add Dry Ingredients

Gradually add:

• Flour
• Salt

Mix until a shaggy dough forms.

---

Step 4: Knead the Dough

Knead for approximately:

8–10 minutes

The dough should become:

• Smooth
• Soft
• Elastic

It may remain slightly tacky.

---

How to Know the Dough Is Ready

Perform the windowpane test.

Stretch a small piece of dough gently.

If it stretches thin without tearing, sufficient gluten has developed.

---

Step 5: First Rise

Place dough into a lightly greased bowl.

Cover with a towel.

1–1½ hours

or until doubled in size.

While the Dough Rises, Prepare the Filling

Step 6: Cook the Blueberries

In a saucepan combine:

Cook over medium heat.

---

Step 7: Thicken the Filling

Stir continuously.

After approximately 5–7 minutes, the mixture will thicken.

Remove from heat.

Add lemon zest.

Why Cooling Matters

Warm filling can soften the dough and make rolling difficult.

A cooled filling creates cleaner layers.
