Rhubarb doesn't seem to grow like that in Southern California, and I thought I had missed the season all together when I spotted a pile of stalks at the Farmer's Market last week and brought home a little over a pound with no particular plans. Then, I remembered that Mrs. Black has posited a rhubarb jam recipe for her young housekeeper readers, and we were off! Apparently, rhubarb appeared in the Glasgow area in April back in the 1880s. Check out this site for more information on the history of rhubarb in Great Britain (including instructions for how to turn rhubarb into organic insecticide!).
Let us hear from Mrs. Black: "At this particular season many people have nearly finished their last year's jam, and the usual jam fruit has not come in. There is no denying that it is much cheaper to make jam at home than to buy it, and it is very easy indeed to make. Get three sweet oranges, and peel them much as you would peel apples, and cut the peel up into chips, but not very finely. Take all the white part off and cut the orange into thin slices, taking the seeds out as you go along. Put all this into a clean pot or stew pan, with 2 lbs. of sugar and let it melt, which it will in a few minutes, then was thoroughly, and cut off in very short pieces 2 lbs. rhubarb, which add to the sugar and oranges in the pan. When it boils up again, let it boil smartly for half-an-hour, then put it in jelly-cans for use. This is not very fine jam, but it is very good indeed, and particularly good to eat with boiled rice or corn-flour. A common pot or pan does quite well for boiling the rhubarb jam, but it is almost absolutely necessary that it be thoroughly scoured and washed with warm water and soap afterwards well dried. A porcelain-lined goblet is as good as any jelly-pan."
I wonder if rhubarb was even more sour back then, or if my Scottish husband's sweet tooth is a cultural thing. Two pounds of rhubarb, two pounds of sugar. And a very happy dentist! I loved the idea of rhubarb and orange, given that strawberry/rhubarb is the more common combination these days. I had a few tangerines in the house, so I peeled and chopped them, leaving out the rind. I peeled the rhubarb a little to get the stringy-est strings off and chopped that up as well. Rather than a pound of sugar for my pound of rhubarb, I added about 1 1/2 cups of sugar. And since I was feeling adventurous, I tied up about 5 sprigs of thyme and threw that in for a little savoury. I was also going for more of a "compote" to use as an ice cream topping, so I added a cup of water to thin it out a bit. It did "boil smartly" for about a half hour, and I had about a pint of sauce for my troubles.
It isn't a "very fine jam," in the velvety smooth sense. The color is also a little weird. A lot of the red rhubarb color seems to cook out, leaving you with a weirdly green/orange color. I'll admit that I'm not the best photographer, but the color you see here is pretty close to the real color. The rhubarb fibers that hung on through the cooking process give a little extra texture to the sauce, the thyme adds a nice hint of freshness, and the orange adds a nice brightness to the whole dish. And when you pour it over premium vanilla ice cream, the resulting melty mass is supremely, lick the bowl delicious. I'm not sure if I'm willing to try it over rice, but I'm sure it would absolutely make corn-flour taste better!
And remember - it is almost absolutely necessary that your pan be thoroughly scoured and washed with warm water and soap. Almost. And a porcelain-lined goblet is as good as any jelly-pan.
