What Makes Buttermilk So Important?

Buttermilk does more than add flavor:

• It keeps muffins moist longer

If you’ve ever wondered why bakery muffins taste so soft — buttermilk is often the reason.

Pro Tips for Perfect Blueberry Muffins

1. Don’t Overmix

Overmixing develops gluten and makes muffins dense.

2. Use Room Temperature Eggs

They incorporate more smoothly.

3. Toss Blueberries in Flour

Prevents sinking and color bleeding.

4. Start with a Hot Oven

375°F gives a nice rise and dome.

5. Use Fresh Blueberries When Possible

They hold shape better during baking.

---

Can I Use Frozen Blueberries?

Yes!

Do not thaw before adding to batter. Toss them in flour and fold in gently.

Frozen berries may slightly tint the batter purple — but flavor remains perfect.
