Gingered Pottage
I experimented with pressure cooking at Pennsic this year, and I can say with certainty that it is a partial success. The pressure cooker would come close to hitting standard pressure, but it never succeeded; I presume this is related to the fact that the prevailing winds cooled the pot in exactly the right ratio to the flames heating the pot to perfectly balance the heat on the edge of pressure. Foods cooked more nicely, as the lid reduces steam and heat loss even if it did not hit pressure. It would be worth dedicating a pressure cooker to the camping stuff if I can find a better cooker for home use.
We tried several things--a cooked turkey breast for Michael that was very delicious, and various "period in principle" vegetable pottages, where the idea is that you prepare a vegetable pottage comprised of period (or period like) ingredients and enjoy an easy lunch. The above pictured is the most successful, comprised of fresh garlic bulbs, a huge chunk of peeled and diced fresh ginger, carrots, potatoes, parsnips, and a rutabaga. Oh, and a bit of salt and pepper to taste. Potatoes are barely period, arriving in the occasional euro cook pot in the 16th century, but I'm not sure about the swede. The earliest reliable reference I can find is a vague description of a seventeenth century record that implies the possibility of unrecorded earlier use.
However, it was very good, and a very reasonable vegetable pottage for a Renaissance persona. If you include the gray area in your time frame, you can eat it without feeling like your place in the space-time continuum is too wretchedly disturbed. And if you can't, sub in one sweet potato and one turnip for a similar flavor and all pre-1601 edible roots.
I generally cooked meat separately for Michael, and he would add it to whatever I made. The primary problem I faced: keeping the meat. If one leaves home with rock solid frozen meat, what one brings has to be cooked within 2 or three days, depending on your cooler. Once cooked, it's only good for 2 or three days. Thus, you can only be sure of having decent meat in the cooler for 4 days, with the expectation that you might get to 6. I am seriously considering for next year precooking meats and keeping a dry-ice cooler, a fresh foods cooler, and a small defrost cooler. As bad as that might sound in terms of gear, it's only the addition of one six-pack sized cooler. I already carry 2 medium coolers to Pennsic and have done so for years.
Most years, I just shop at Giant Eagle for food when I get there, but I did pantry shopping this year--I looked at what I had on hand and just brought food from home. This worked out fine, as well--better, in some ways, as much of what was in the fridge would have had to be thrown out upon my arrival home. This fact also makes me think that the dry ice/wet ice/defrost system is going to be a better idea.
The food court at Pennsic is always something of a challenge. There is very little there for strictly vegan fare, but you can do okay if you allow eggs, dairy, or both into your vegetarianism or your piscetarianism. I did find myself in the position of "eat dairy or starve" a couple of times, so I tried the spinach wrap at Once Again/Nobleman's Inn and the Spinach Pie at Fruity Cobbler. These are the things I ate and can recommend as edible that can fit with a picetarian + dairy food style:
*French Fries from various vendors: I found I liked the ones at Nobleman/Once Again's best.
*Spinach Wrap from the same tent.
*Falafel from Fruity Cobbler. Spinach Pie was okay, but I preferred the Spinach Wrap, above.
*Shrimp and Vegetable stir fries from Delights of Cathy--be aware, however, that they do cook everything in the same woks. Their portion sizes have also gone down.
*Vegetable dishes from Cock & Bull (sauce may be butter or margarine, I didn't ask. Having already had feta cheese by that time, it hardly mattered which was used when faced by my huge-o-matic hunger).
There were other dishes I could have tried, but generally, if I was up in the food court and faced with uncontrollable hunger, I gravitated to the french fries, being the best way to control the hunger and not have to fret about how it was cooked.
