Meat preservation was by salting or smoking, or, most commonly and simply, by keeping the meat alive till needed. Salting was done by two methods. Dry-salting meant burying the meat in a bed of salt pounded to a powder with mortar and pestle. Brine-curing consisted of immersing the meat in a strong salt solution. Before cooking, the salted meat had to be soaked and rinsed.

In addition to roasting and stewing, meat might be pounded to a paste, mixed with other ingredients, and served as a kind of custard. A dish of this kind was blankmanger, consisting of a paste of chicken blended with rice boiled in almond milk, seasoned with sugar, cooked until very thick, and garnished with fried almonds and anise. Another was mortrews, of fish or meat that was pounded, mixed with bread crumbs, stock, and eggs, and poached, producing a kind of quenelle, or dumpling. Both meat and fish were also made into pies, pasties, and fritters.

Sauces were made from herbs from the castle garden that were ground to a paste, mixed with wine, verjuice (the juice of unripe grapes), vinegar, onions, ginger, pepper, saffron, cloves, and cinnamon. Mustard, a favorite ingredient, was used by the gallon.

 

The most common vegetables, besides onions and garlic, were peas and beans. Staples of the diet of the poor, for the rich they might be served with onions and saffron. Honey, commonly used for sweetening, came from castle or manor beas; fruit from the castle orchard - apples, pears, plums, and peaches - was supplemented by wild fruits and nuts from the lord's wood. In addition to these local products, there were imported luxuries such as sugar (including a special kind made with roses and violets), rice, almonds, figs, dates, raisins, oranges, and pomegranates, purchased in town or at the fairs. Ordinary sugar was bought by the loaf and had to be pounded; powdered white sugar was more expensive.
