oven doesn't get hot enough to make biscuits. Is there any alternative?
Do you have a grill? I've made crisps and cobblers on the grill with success.
In a Dutch oven, a la campfire cookery.
I would have my oven calibrated. A standard oven should not have problems getting hot enough to bake biscuits.
You CAN bake them at a lower temperature...they just won't rise as much.
