ryanpeek / DO_camping_recipes

Created September 2, 2017 06:42

DO_Camping_Recipes

	These are a smattering of relatively well-tested Dutch Oven (DO) recipes I've used during camping trips over the last few years (to great success)!. I just wanted to start putting them in one place. All of these pretty much use a 12" DO and depending on the dish, between 15-30 briquettes. I may abbreviate things, so C=cup, TBSP=tablespoon, TSP=teaspoon.

	# Brownies (1 box serves ~8)

	You'll need a spoon and a healthy appetite for chocolate.

	## Ingredients

	- 1 box dry brownie mix
	- Depending on the mix, 2-3 eggs
