“Deer tendon does not soften easily. For the first three days of preparations, one must pound and boil the tendons several times, while continually wringing out any foul-smelling juices from within it. Next, braise the deer tendon in pork broth and then after that braise it in chicken broth. Add autumn sauce, wine, and starch to thicken and reduce the cooking liquid.
The tendon can be served as-is as a white-cooked dish without addition of anything else. They can also be braised together with ham, winter bamboo shoots, and shitake until they take on a reddish hue and then served in a bowl without reduction. To finish the white-cooked dish, sprinkle it with finely ground Szechuan pepper.”
While I buy beef tendon and eat it often enough, I have never had deer tendon. And unless I have to chance to go deer hunting one of these days, I highly doubt I will. Coming at more than $100CAD per kg in dried form, deer tendon is not exactly cheap especially considering that beef tendon is usually much less than a tenth of the price. Truth is, if their texture and flavours are anywhere similar to one other, I’m not sure why I would pay anything close to eat the former.
Regardless, this recipe is still rather informative since it shows one how to reconstitute and process dried deer tendon, at least in the way the people in Qing Dynasty did it. The technique is the same as most dried texture foods used in Chinese cuisine (like sharks fin or sea cucumber) but with more pounding and wringing. Basically, you are trying to purge the ingredients of all its original smells and tastes, fill it with the flavours of a good meat broth, and then use in your recipe.
The two methods of preparing deer tendon described here probably works well enough for fresh pork and beef tendon. That said they still probably cannot beat a plate of mala tendon (麻辣牛筋).
List of Essential knowledge::Cleaning
The requirements of cleaning and washing specific ingredients are as follows; one must remove all feathers from bird’s nest, remove all mud from within sea cucumbers, remove all sand from shark’s fin, and wash the foul smells from deer tendon. If the meat contain sinews, one needs to remove them such that the meat can remain tender after cooking. Duck kidneys have a foul odour , therefore be sure to remove them and rinse the cavity well. Be careful to not break the fish’s gall bladder when gutting and cleaning the fish since doing so will render the entire dish bitter. If one does not wash away the saliva of an eel during its preparation, the resulting dish will have an unpleasant fishy odour. One must remove the old leaves when cleaning garlic chive, leaving only the tender white stems. When preparing leaf vegetables, one should remove the coarser outside leaves and use only the heart. In Nei-Ze (禮記::內則) it is said: “One should remove the orbital bone around a fish’s eyes and remove the orifices  of the soft shell turtle.”, admonishing us to diligently clean the ingredients for a dish . The common proverb: “If you want a fish to taste good, you will have to clean it extremely well.” , also highlights the truth behind these facts.
: One can also read the text as “Ducks have a foul urine-like kidney odour, make sure to clean it (and it’s insides) well to remove the smell.” So, either the duck’s kidneys smells bad, or the duck has bad kidney smells. Your pick.
: I have no idea what “醜” are. It says here they are “perforated openings of the turtle”. What does that even mean? Nostrils? Cloaca? Mouth? Ears? I’m going saying “orifices” here for the sake of generality.
: The full text is in here. Basically, the whole sentence tells what to do with animals in cleaning and preparations. Did you know you should remove the head of a badger and the intestines of a wolf when preparing them? I didn’t.
: The Chinese text says “To make fish taste good, wash it until the white tendons/nerves come out”. Basically what’s being said here is that you have to wash the fish very well, right? At first I thought this was indeed the case and the white tendon part was simply exaggeration for humour. That is, until I read this. It appears that there ARE long white strands of nerves tissues that you have to remove from each side of the spine near the gills to really rid a fish such as carp of its strong fishy smells.
