Here's a fun video from Tasting History on a panettone recipe from the 1890s that uses baking soda instead of yeast. It also includes some history - mostly debunking the history - of the bread. There is an embedded commercial, but you could fast-forward past it.

Me too - open this morning, private this afternoon. The creator of the channel lives in Los Angeles, and I bet the fires have caused this. Meanwhile, many or all of his videos are on Youtube, although maybe with very annoying ads.
Here it is on YouTube -

Here is the recipe...
Ingredients:
Instructions:
P.s. the recipe calls for cream of tartar + baking soda. Isn't that baking powder? If so, how much baking powder could one use to replace both? 15g?
There are several formulations for baking power, at least in the US. For one thing there are the double-acting vs single-acting ones. But yes, adding cream of tartar is one.
When I looked into baking soda a while ago, I learned that 1/4 tsp is enough to leaven 1 cup of flour. I would expect to use 1.5 tsp of baking soda per cup of flour for biscuits (UK: scones). OTOH, I've also seen statements that you need 2 - 3 times as much baking powder as baking soda, so I'm a little confused.
One search result gave me a 2:1 ratio of cream of tartar + baking soda, to make baking powder, which is exactly like in the recipe. So i'm assuming one could swap the 10g tartar and 5g baking soda for 15g baking powder.
