Last time I suggested Pemmican and we're continuing to suggest it.
Food Items made with items we already have
Pemmican - 1 meat, 1 animal fat, 1 berries
Yam "Caramel" - Cooked Yam (see comment below for what this is based off of)
Tree Sap - Tap "wood" nodes to collect sap in warmer "seasons", process into syrup
Yam Oil - Also has industrial applications, since we're making bio-fuel from yams we're technically already doing this
Vinegar - made with berries used for preserving or improving flavor
Yam Greens - Harvested from Yam plants
New food items:
Gelatin - rendered from cooking meat. Used to thicken stews and possibly make gummie treats with red berries for joint health and morale.
Tatonka manure - We want to check it for Nitrate content. We know it's good to give to the food/water alge, but how's the nitrate content? Does it contain the same impurities as the regular water/soil? Can we use it as fertilizer to boost yields? Yeah, I know "tatonka manure collection detail" is a sucky job but if it can boost algae/crop output, we should be doing it.
