Preheat oven to 375.

Mix flour, brown sugar and shortening into crumbs. Split the crumb mixture in half. Set the one half aside for crumbs.

Pour the King Syrup in the other half of the crumb mixture. Mix the baking soda in the boiling water. When this fizzes, pour on top of the king syrup/crumb mixture. If the soda/water doesn't fizz, you didn't get your water hot enough or your baking soda is bad. Dump out water and try again. Pie won't rise if it doesn't fizz. Add 1 beaten egg. Mix with fork.

Pour in unbaked pie shell. If you don't want to make your own shell, just use one of those fold out pillsbury ones. Top with crumbs.

Bake in preheated 375 oven. Bake 10 minutes. Don't open the door, turn oven down to 350. Bake an additional 30-40 minutes.
