How do I install extra mods into Tekkit Classic?

[ANIMANIAC250]

I'm trying to install some mods into tekkit classic but all the youtube vids that ive watched arent helping. I'm trying to install some cooking mods or like food mods. If someone could help me with this that would be awesome.

Thanks,

You need to make sure you've run tekkit once. Go to 

%APPDATA%.technicmodpackstekkitmain

 Put "Core" Mods (i.e. .jar files labeled Core) in the Coremods folder in that directory, put mods compatible with forge mod loader in the mods folder. If you want to install Optifine (or something that can't be installed via FML), do it the old fashioned way, but put the files into the Modpack.jar in the Bin folder.

Wait, you're trying to add a modpack onto a modpack? That won't work. Tekkit Classic changes item values (using one value, then a damage value) and might interfere with the item value changes made to the foodpack...
