This is where the Long Egg comes in. Long hens became extinct aeons ago (possibly from exhaustion during the never-ending egg-laying), so these days we have to resort to
I rummaged around the kitchen and came up with a squeezy sauce bottle that seemed to be about the right diameter for the outer tube, so I cut the top off. The inner tube was more problematic, but I found some phallic pet feeder things that were only a little too big for the inner tube (I figured that was okay - more yolk, less white - only doctors like egg white anyway) in the local Chino.
I poured my yolks into one of the blue tubes, but was unable to seal the top so I had to rig up something with toothpicks and wire to keep the tube vertical while the yolks set. When it was done, I placed the long yolk into the wider tube, poured albumen around it and popped it back into the pan until it set. Getting the complete long egg out of the tube was a bit of a disaster, however. I hadn't thought to use any lubricant, and the egg white had become quite firmly attached to the polythene. So I had to cut it out with a knife and ended up with a somewhat mis-shapen long egg.
I had my pastry, jelly and pork filling all ready, and no time (or eggs) to make another long egg, so I chucked it in and baked it.
So the egg didn't look great, but the whole pie tasted fantastic.
That was a couple of weeks ago. I made another long egg this morning, using food-grade polythene tubes that I made myself using my heat-sealer. This one seems to have turned out pretty well, so I'll make another gala pie tomorrow. Wish me luck.
