Look at the recipe's source. Morgans. They sell extracts, not grains.Jovial_Monk said:why use an extract, rather than steeping some crushed crystal?
I agree with your recipe modifications. I'm a partial masher. Where I to make this, I'd go 1Kg Pale Ale Malt & 200g Dark Crystal, mashed. 2 Kg Light DME, E Kent Goldings for aroma and whatever high AA I had on hand for bittering.
