Of course the first recipe I try is one of those recipes that isn't actually written down, but passed on by word of mouth. For example, ingredient amounts vary wildly (1/2 to 1 cup of coconut?), a lack of pan size (20 x 20 cm? 20 x 30? It's a mystery!) and a lack of baking time - just "bake until done".
Still, I guess that once I make more of these more free-form CWA recipes I'll eventually get good at the guessing ;)
