K, here's exactly what you need to do.  Fill pot with fresh water ( you can use the pots by the top of the stream) Put a rock in the fire to get a hot rock.  When rock turns red, put rock on pot and you get boiling water.  Use one sweet herb, one soapy herb, and one spicy herb on pot.  Drop a villager on the food bin to put food in pot.  For the other ingredients, you need a flying fish (blue), a mushroom, a cooked fruit from the tree, and a mushroom.  For flying fish, drop a villager, preferably one with farming experience cuz it makes it easier, on the pier.  He/she will add fish to pot.  Drop villager on fruit tree and he/she will cook fruit and add it to the pot.  Drop villager on the blackberry bush and he/she will add a bowl of blackberries to the pot.  Drop a child on a mushroom and he/she will add it to the pot. You may have to wait for a mushroom to appear, but you can hit spacebar to pause the game so you can drag the child to the mushroom. Et voila, you have The Grand Feast!
