After some debate, I placed all three interpretations from Two fifteenth-century cookery-books : Harleian MS. 279 (ab 1430), & Harl. MS. 4016 (ab. 1450), with extracts from Ashmole MS. 1439, Laud MS. 553, & Douce MS. 55 Thomas Austin for tench in sauce or broth on the same blog post. My reasoning for this is that they have more similarities than differences. The Tenche in Cyueye includes onions, the Tenche in Bruette does not and the Rapeye can be made with various fishes (including tench) and includes different raisins and spices.
The Glossary of Medieval & Renaissance Culinary Terms defines cyueye in the following way:
cive, civey(e), ciuey, cyuey, ceue, cyueye = Ragout or stew (possibly derived from a word meaning 'onion' (Plouvier). (Viandier) - Among other modern usages, this is probably a derivative of civey, which was at one time named for, and characterized by, the possibility of thickening a sauce with finely chopped onion, cooked till very soft. Some medieval recipes for civeys (for example, hare in civey) also call for blood as an additional thickener; nowadays the dish, which is now sometimes called civet, is mostly characterized by thickening and enriching the broth with the reserved blood of the critter you're cooking. It will coagulate if boiled, and turn very dark, but if heated properly it will assume a velvety texture similar to a stirred custard, and acquire a deep russet shade almost like a mole-poblano-type sauce. (Troy)I was intrigued by the instructions to scald or boil the fish before roasting it. Scalding is a method of cleaning and killing any microorganisms that might be harmful. It involves heating a liquid (in this case water) or milk to just below boiling. If you have a thermometer 180 degrees is best. If you don't you want to keep an eye on the side of the pan. You can remove your liquid when you see small bubbles forming around the side and steam starting to wisp off the pan.
Original Recipe
.lxxxxiiij. Tenche in bruette.—Take þe Tenche, an sethe hem & roste hem, an grynde Pepir an Safroun, Bred and Ale, & tempere wyth þe brothe, an boyle it; þen take þe Tenche y-rostyd, an ley hym on a chargeoure; þan ley on þe sewe a-boue
Interpretation
94. Tench in Broth- Take the tench, and boil him and roast him, and grind pepper and saffron, bread and ale, and temper with the broth, and boil it, then take the tench roasted, and lay him on a charger; then lay on the sauce above.
Ingredients - Serves 1 as Main, 2 as side
1/4 pound fatty firm textured fish such as carp, perch, tench, bluefish or bass
1/4 tsp. pepper
pinch of saffron
1/4 cup dried bread crumbs
3/4 cup ale
3 tbsp. fish broth
Instructions In keeping with the instructions, I scalded the fish by placing it in a pot with just enough water to cover it. I then heated the pan until I saw small bubbles forming around the edge of it and steam starting to form. Due to modern methods of cleaning and butchering fish, I imagine you could have skipped this step without difficulty.
I removed the fish from the pan and placed it on a lightly oiled baking sheet and roasted it in the oven until it was done. While the fish was cooking in the oven I took a few tablespoons of the broth and added the saffron to it. Once the saffron had strongly colored the water, I added it to the ale (ok confession time--I used Sam Adams Summer Shandy made with lemon peel and grains of paradise) and then soaked the bread crumbs in it. Once the bread was soggy I put it in the pot and brought it to a boil until it formed a thick sauce. After the fish had finished cooking I plated and served it.
