I would not go that way myself, if you want real cooking (wich is fun), you have to create a really complex application, or to script one by one each recipt as a interactive minigame (you could problably find many common code among each minigame but those are all separed). You for sure don't want to keep into account real chemistry, because you'll need massive computing power (however you can get inspiration for most commond results, like over heating brea in oven make it become burned).
Those games you mentioned are fun and most important are viable to program as games. They took significative elements from real cooking, but nothing more, though if you are determined you could make a game in your way and that would be fun, but I warn you that will be really hard and frustrating.
what kind of gameplay you are searching for?
- realistic simulation? basically a interactive video
- hard-core hand-eye coordination? cook what required in a certain time
- causal gaming? do recipes without any real challenge but the pleasure to see something created
- perfection? (swipe in a certain direction at a certain speed)
- economic? (buy upgrades and make income from selling food)
Personally I'm ultra bored by those cooking games, there are some different but mostly they are clones of each other. I hope you could really innovate the gender!
