Half batch to test the recipe. Used 3/4c AP GF flour and topped up with a mix of sorghum and brown rice. Added ~1/4tsp xanthan and 1/2tsp potato powder to flesh out the flour blend. Added cardamom and a sprinkle of cinnamon. Let autolyze 30 minutes while the oven preheated then added the leaveners and berries. Had to add extra creamer and water to get a less stodgey consistency. I think that was good — they rose well. Done @ 25 minutes. No streusel topping.
