Idea: Cooking timer site

Here's an idea for a cool little website, free of charge for anyone who decides to develop it:

Target audience is home cookers. Anyone who's cooked a meal knows how difficult it is to time all the cooking-related activities - when to cut stuff, when to start defrosting, when to put something in the oven, etc, etc.

So the idea is as follows: You upload all the recipes for a meal you want to prepare to the website. You then define the time you have available for preparations and any breaks you need in the middle ('pick up the kid from school - 30 mins').

The site then calculates and optimizes a step-by-step timeline of what you need to do in order to accomplish all the dishes, and have them ready at the perfect timing for serving to the table.

For example:

1:45 - defrost chicken
1:51 - pre-heat oven
1:52 - chop 4 onions
1:57 - melt chocolate
Etc, etc.

A v.2 of this site might also optimize a shopping list for you, combining all the ingredients for all the items on your menu.

Not sure you can make money off it (OK - slap a few Google ads on it...), but I sure would use it!
