Can I make soda bread without buttermilk?
Yes. For a reliable homemade substitute, mix 1 3/4 cups milk with 1 3/4 tablespoons lemon juice or white vinegar. Let it sit 5 to 10 minutes, then use it like buttermilk. Real buttermilk gives the best flavor and tenderness, but the swap works.
Why cut a cross on top?
It helps the loaf expand evenly and bake through the center. Also, it gives you those extra crisp ridges, which are basically the best bites.
How do I know when it is done?
Look for a deep golden crust and an internal temperature around 195 to 205°F. If you do not have a thermometer, tap the bottom. It should sound hollow.
My soda bread turned out tough. What happened?
The usual culprit is overmixing or overhandling. Stir just until the flour disappears, then shape gently. Also make sure your baking soda is fresh.
My loaf is dry or crumbly. How do I fix that?
Dry soda bread usually comes from too little buttermilk or a slightly long bake. Next time, keep the dough soft and a little sticky, and start checking at the early end of the bake window. Wrapping the fully cooled loaf will also help it stay tender.
Why is the center dense?
A dense center can happen if the baking soda is old, the dough is handled too much, or the loaf is shaped too tall. Use fresh baking soda, keep mixing gentle, and pat the round to about 1 1/2 inches thick so it bakes through evenly.
Can I add raisins or herbs?
Absolutely. Add-ins work best with a light touch. Stir them into the flour mixture after rubbing in the butter, then add the buttermilk. Fold in 3/4 cup raisins for a sweet loaf, or add 1 to 2 tablespoons chopped herbs plus a little black pepper for savory. Keep add-ins modest so the bread still bakes evenly.
