So, I made them, found them good, and eventually crumpets appeared in the refrigerated section of the grocery stores here and looked much like my homemade version. I don't think I've made them at home since the grocery store version appeared, though homemade area certainly superior.
Now, The Baking Bible version: this is a fast recipe for one involving yeast, and as it's a small batch (1 cup of flour) it doesn't even need to dirty more than a bowl and some measuring spoons. I mixed my flour, yeast, touch of sugar, and salt with a whisk, added the warm water, beat the mixture for a bit with the whisk, then (in nostalgia for the Good Cook technique) slapped the batter around with my hand for a bit. My first rise was done after an hour, in went baking soda in a bit of almond milk, then the batter got a further 30 minutes to bubble away some more.
I used my electric griddle for the baking, and found the recommended temperature was too high--my crumpets got a bit too brown before they cooked through, even though they were thinner than I really like them. Next time, I'll add more batter to my shallow crumpet rings and try to hit that balance between full and running over.
