Searched for nests in the trees until I realized that this is fiction

it would be Good to fix baked potatoes and he will prepare the coals without a grate. Add more recipes, such as fried potatoes with meat, fried potatoes with mushrooms, pizza... In the loot drops a little number of items: one nail, three coin, single arrowhead... Garbage bags in the woods all empty. After drinking meat stew is not refundable empty glass jar.
I don't understand some of this, but I'll do my best.
For cooking, I followed a simple rule. If you need water, then you use the pot. If you don't need water, then you use the grill. Maybe you're asking to cook a potato without the grill? As far as I know, you need a grill or foil or
something so that the potato doesn't burn.
At this time, I don't think ComSenMod will add any new assets to the game. There are other mods that do that. The goal of ComSenMod is to fill things out: to make the most of what's already in the game. So unfortunately pizza isn't feasible. However it would be nice to find some recipe to use animal fat - I see it as an underutilized resource.
In ComSenMod you find more things like nails, coins, and arrowheads in one container. You need a lot of these things to be very useful, so ComSenMod gives you more at once in hopes of reducing clutter.
It doesn't make sense that you lose the glass jar when you cook stew... but it doesn't make sense for the jar to reappear when you eat the stew, either. It's not a jar of stew, it's a bowl of stew. I think the common sense solution for this would be to change the model from a glass jar into a disposable paper cup. Then it would make sense that the container disappears when you cook the stew. However, I'm hesitant to make the jump from xml edits to new artwork, because it'll probably make it harder to use ComSenMod in multiplayer.
This is kind of like requiring a candle to make a campfire - in my mind, the candle is actually a butane lighter.

Then when I tried it, I realized candles are only found in one or two houses, so I allowed torches as well. Everyone starts with a torch, but it creates an interesting choice in the early game, and I can speak from experience that losing that first campfire before you've made any tallow creates a major survival setback.
Currently I'm thinking about replacing some or all instances of bottled water with murky water, off a suggestion by Roland. What makes common sense here kind of depends on the nature of the zombie apocalypse - is it a super virulent strain of airborne pathogen that can permeate into nearly anything? If so, then other beverages you find are also probably bad. If not, then a lot of sealed bottles of water still exist that should be fine.
There's also balance to consider. You find less water in ComSenMod because female zombies drop generic loot. Is that a big enough reduction to the amount of clean water you find? I'm doing my best to judge from my own playthroughs, but it's hard to draw a conclusion based on one person.
