I made an ordinary bitter a while back and used 1/2 a lb. of crisp amber malt, it had a very similar flavor. So this is what I'm going to try:
5.5 us gal
malt
10 lbs. rahr 2-row
1 lb. muntons crystal 50-60
.5 lbs. crisp amber
2 oz. roasted barley
hops
1.5 oz. ekg @ 5.0 aa (60)
.5 oz. ekg (5)
yeast S-04
I'll let you all know how it turns out, Cheers.
