Just look for a California common recipe. Anchor Steam is the style, so every good Cali common is pretty much trying to clone anchor steam.
Of the top of my head (literally)
10oz Crystal 40
10oz Crystal 80
1oz Northern Brewer @ 60min
0.5oz NB @15
0.5oz NB @5
0.5oz NB @0
Dry hop with 0.5oz NB
Wyeast 2112/WLP810 - this is critical, you have to use this yeast strain.
Every clone, is going to be VERY close to that. Lots of crystal, 100% northern brewer hops , and 2112/WLP007 yeast.
