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)
7lbs 2-row
1oz Munich
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.
