This is a basic mix to start with when you're planning a camping trip. Use it to make dumplings, pancakes, and fruit cobblers. If you travel with more 'stuff' you can bake biscuits and short cakes too.
If you're going to be out a week or more in the height of the summer, leave out the margarine. Otherwise, squeeze margarine travels very well; we never had it go bad despite several 4-6 day trips in the Virginia summer. Very easily doubled or tripled.
For variety, add a tablespoon caraway seeds to this mix, or add 1 cup grated cheese when you add the beer. If you're really daring, add the cheese AND the seeds! This bread can also be baked as drop biscuits, just bake 12 minutes at 400°F.
