Herbs and beans
I don't use herbs and coffee beans much in my game. In fact, I don't think I've ever made coffee.
I'm playing an apocalypse/nothing is free mashup challenge right now, and since there is no grocery store, I'm limited to only using ingredients my sims grow from seeds they find. Early on, any variety is precious, especially because I need 8 varieties of perfect plants.
However, most of the seeds my sims receive upon hitting Gardening level 1 aren't food - coffee beans, herbs, and alchemy ingredients. (In the way of edible plants, I currently have lettuce, grapes, onions, and white caps. I'd kill for a tomato.) It makes me wonder if there's more to be done with herbs and coffee.
