I remember Arx Fatalis were you could bake apple pies from scratch. you could even add some wine to it to spike the pie.
It had no effect on the game, spiked or not, except that you got hitpoints back.
But the baking was fun and reduced the clutter of apples, water and flour in the looting bags

I just ticked off a bit the blacksmith for abusing his fireplace for a baking stove. But nothing what a spiked pie could have fixed ;p
