I have used Big Oven for my OAMC cooking session.  Right after Christmas my Mother-in-law and my sister-in-law and I spent a day making meals.  Using Big Oven was really easy and saved us a lot of time!  Once I entered the recipes we were going to use, I added them to our menu for cooking day.  I also was sure to adjust the "servings" for each meal to make 3 meals (one for each of us).  Big Oven did all of the hard work, multiplying ingredients, etc...  I printed out the shopping list that combined ingredients for us.  I checked the pantry and then shopped for our items.  We also printed out the recipes and stuck it on top of the completed dish so we had all of the baking instructions right there.  That is great if you give a meal away too!  Hope it works well for you!  I am looking forward to adding more recipes.  It will be easier to plan a meal sessin if all of my recipes are in Big Oven!
