Question: What kind of cinnamon did they use in period?
Short Answer: There's no way to be sure.
Long Answer:
Cinnamon is a rather tricky spice because there are a bunch of different, related spices that are all referred to by that name.
Ceylon Cinnamon (Cinnamomum zeylanicum or sometimes Cinnamomum verum): also referred to as "True Cinnamon". This cinnamon is the preferred variety in Europe and Mexico. It is milder than Cassia, but has a more subtle and complex flavor. The dried, unripe berries of this plant are sold as "Cassia buds".
Cassia (Cinnamomum cassia): also known as "Chinese Cinnamon". This is what is sold as Cinnamon in the United States (the Food, Drug and Cosmetic Act of 1938 permits spice traders to label cassia as cinnamon). Cassia was often referred to as "Canelle" in medieval English and French cookbooks.
Indonesian Cinnamon (Cinnamomum burmannii): also known as "Korintje Cinnamon". This cinnamon is not quite as strong as Cassia.
Vietnamese Cinnamon (Cinnamomum loureirii): Of the different kinds of cinnamon, this is the strongest.
In the glossary of his translation of The Viandier of Taillevent, Terence Scully has the following definitions:
canelle, cannelle: common cinnamon from cassia bark or buds pouldre de canelle: a finer cinnamon, also called cynamome fleur de canelle: (ground) cassia bark or buds cynamome: a fine type of cinnamon from cinnamon bark (cf. the Tractatus (II, §11), which distinguishes between cynamomum and canellam: "Ad homines simplices et mediocres sufficiat ... canella") |
From this there is the implication that canelle was Cassia (Cinnamomum cassia) and cynamome was Cinnamon (Cinnamomum zeylanicum). This is further supported by the recipes below, where both canelle and cinnamon appear, and therefore are unlikely to refer to the same spice.

In contradiction of the above, in the recipe below there is a clear implication that cinnamon (or at least some cinnamon) is considered to be canelle.
Recipe VI [K6]. Quomodo temperetur salsum dominorum et quamdiu durat. Man skal takæ gørfærs naghlæ, oc muscat, cardemomum, pipær, cinamomum thæt ær kaniæl, oc ingifær, allæ iæfn wæghnæ, tho swa at kaniæl ær æm mykæt sum allæ hinæ andræ; oc slyk to stekt brøth sum allæ hinæ andræ, oc støtæ them allæ samæ, oc malæ mæth stærk ædykæ oc latæ i en læghæl. Thæt ær hærræ salsæ, oc ær goth et halft aar. [emphasis added] Recipe VI [K6]. How to prepare a sauce for the lords and how long it lasts. One takes cloves and nutmeg, cardamom, pepper, cinnamon - that is canel - and ginger, all in equal amounts, except that there should be as much canel as all the other spices; and add twice as much toasted bread as of everything else, and grind them all together, and blend with strong vinegar, and place it in a cask. This is a lordly sauce, and it is good for half a year. [emphasis added] Source: Libellus De Arte Coquinaria, Vincent F. Cuenca (trans.), Rudolf Grewe (ed.), Constance B. Hieatt (ed.) |
The matter is not at all clear for other texts. Both spices were grown in southeast Asia and both were imported into Europe in period, and since they're very closely related it is very easy to confuse the two. One can also easily imagine that the two were sometimes mixed together by spice merchants, and that the quality of either could vary greatly due to the amount of time it took to get them from the far east to Europe.
If the above wasn't confusing enough, a quick check of two early dictionaries completely fails to shed any light on the subject.
Canelle: f. (Our moderne cannell, or cinnamon (Looke Cinnamome) Cinnamome: f. Cinnamon: (Some learned men are of opinion, that the true Cinnamon of the Ancients (being a wood, and not, as ours, the barke of a tree) is hardlie to be found at this day; and that the rinde, or barke, which we commonly hold to be Cinnamon, is much inferior unto it, and should rather be tearmed, Cassia, and Canella.) Source: A Dictionarie of the French and English Tongues, R. Cotgrave (1611) |
Canellàre, to Cinnamond. Cannella, a litle cane, reede or pipe. Also a flute or recorder. Also a tap or spiggot. Also the arme-bone of a man. Also the spice Cinnamond. Cannellàta, a kind of Cinnamond meat. Cassia, the drug Cassia or Canell. Source: Queen Anna's New World of Words, J. Florio (1611) |
From these definitions it can be inferred that either the French and the Italians didn't make much of a distinction between the types of cinnamon, or that the English dictionary maker didn't.
