I kind of cobbled together two recipes, and it came out all right, though it doesn’t rise very much:

Mix together in one bowl: 4 cups almond flour 1.5 tsp baking soda 1/4 tsp salt

And in another bowl 2 eggs 2 tbsp honey or maple syrup 3/4 cup buttermilk

Then combine wet and dry ingredients, add about a cup of currants, and roll into a ball, cut a cross shape into it. Press into a round pan (I used the lid of the cast-iron dutch oven) and put into a preheated 350 oven.

Bake for 30 minutes, let sit in the hot oven another 10 minutes, then let it cool at least 30 minutes before serving
