Perhaps it is the desert that will surprise people most. The prior was frequently treated to almonds and rice. In medieval Europe rice was served in a pudding made from almond milk. Interestingly figs and walnuts were also available in 14th century Dublin.
Alas, they don't mention the trade routes that would bring these Mediterranean ingredients (along with another ingredient mentioned: Olive Oil) to the rich in Dublin.
Stefan has some recipes here...
Here is a Tudor era recipe for rice pudding (although using sausage casing would probably taste better than his modern method):
Original recipe from Gervase Markham's The English Hous-Wife, 1615: Takehalfe a pound of Rice, and steep it in new Milk a whole night, and in themorning drain it, and let the Milk drop away, and take a quart of the best,sweetest, and thickest Cream, and put the Rice into it, and boyl it a little.Then set it to cool and hour or two, and after put in the yolkes of half adozen Eggs, a little Pepper, Cloves, Mace, Currants, Dates, Sugar, and Salt,put in a great store of Beef suet well beaten, and small shred, and so put itinto the farms and boyl them as before shewed, and serve them after a day old.
Coquinaria has a Catalonian recipe and discussion HERE.
Rice remained a fairly expensive import for most of the Middle Ages and was grown in northern Italy only towards the end of the period.they also note that bread was not common in northern Europe
Before the 14th century bread was not as common among the lower classes, especially in the north where wheat was more difficult to grow. A bread-based diet became gradually more common during the 15th century and replaced warm intermediate meals that were porridge- or gruel-based. Leavened bread was more common in wheat-growing regions in the south, while unleavened flatbread of barley, rye or oats remained more common in northern and highland regions, and unleavened flatbread was also common as provisions for troops.I first noticed this in the novel Kristin Lavransdatter, where she gave out gruel (aka oatmeal) to guests.
Yet Oats were grown in Scandanavia since Bronze age times, LINK
