The ice cream scoop as fisheye lense of the kitchen world.
By the way, I bought this spring action lever type scoop to use for filling cupcake papers. I read that a 1/4 cup capacity scoop will fill a normal size tin 2/3rds of the way. A 1/3 cup capacity scoop will fill the tin 3/4ths of the way. This is a just over 1/4 cup capacity scoop, it's a half sphere shape and has a diameter of 2.5 inches. The guy at the store was nice enough to use water to check the capacity of this scoop in the store for me.
Update: This scoop fills the paper liners almost to the top! I'll have to try a smaller scoop instead. Also, I think, but I'm not sure, the scoop had the number 20 (nope) 12 on it.
Updated update July 19th: I exchanged the scoop for a 2 and 3/4 Tablespoon capacity scoop, it's 1.75 inches in diameter and has the number 24 on it. I hope it will allow me to be goopy and sort of messy and yet get the cupcake to rise the right point. More later.
Update the Third: August 2nd, 2005. A comedy of errors proportion exchange has gone on and I now have a 4 Tablespoon (nearly 1/4 C) capacity, 2.25 diameter scoop which works fine. It allows for the messy nature of the batter without overfilling. Has the number 16 on it.
I have forgotten the scoop capacity needed for mini tins and large tin sizes, if you know please chime in.
