For those cooks under fifty years of age - therefore not so highly skilled their produce is beyond the reach of the charitable institutions - you may sell meals (providing they are cooked by your hand) to any of the following four locales: the Silverfalls Mission, the Parrian Mission, Laphacles' Tea Rooms in Thakria or the Bakery of Dalphuin in Mercinae. The missions have two base prices: one for meals cooked very recently and therefore considered absolutely fresh, and another for meals cooked a while back. The former is, of course, the greater remuneration.
Additionally, more gold is paid for meals that include desserts - an extra fifty percent for basic types (like single fruit or nuts), twice the basic value for full size varities (like fruit medley or apple pie). Meals cooked by another hand designated fresh cannot be sold save by their chefs, though older meals can be sold by anyone.
