Fine, it's a pate a choux. A Gougeres (pretend there's one of those accent things over the first "e'). Whatever. Melt a LOT of butter in water.
Dump in a bunch of flour, and start stirring. This will get really thick.
Your arm will begin to hurt, because then you want to take it off the heat, and add an egg, stirring until it's fully incorporated.
SIX TIMES.
It's going to get both fluffy and stickily heavy at the same time. Ready? Add the cheese. Stir some more.
Dump the whole mess into a ziplok bag and snip off a corner. Or, if you're fancy, load it into a pastry bag.
Squeeze out puff-sized blops onto a buttered cookie sheet.
Dab each one with a wash of egg and water, then bake until golden.
Try not to look too greedy when you eat them.
PS - thanks to mom for the recipe!
