There are two items that I wish to see in this plugin:
1) A recipe multiplier. Many recipe followers cannot make much adjustment to a recipe. So they either make a recipe with ingredients for 6 and one person eat it for days OR don't cook that dish at all.
2) Add an "unattended cooking time" to the times of a recipe. Some dishes take minutes to put together and an extended time to cook. A dish may baking unattended for an hour or requiring constant stirring for that same hour.
Add #1 and I'll change to 5 stars. Both will get 6!
