I was ecstatic to find a high-quality Scottish Oatmeal available in the United States. I lived in Scotland in the 1970s. I brought a package of oatmeal (ground, not rolled -- rolled oats were completely unavailable and unheard of where I was living) back to the USA with me and kept it sealed in Tupperware, hoping to find something similar.
I cooked up a pot of Hamlyn's, and also cooked up the last of my carefully preserved oatmeal brought from Scotland, so I could compare them. Hamlyn's is the right stuff!
Perhaps the soil the oats are grown in makes a difference.
Bob's Red Mill Scottish-style oatmeal and other US-grown alternatives were very close, but the taste is not the same.
I had to find another source of Scottish oatmeal when Bob's Red Mill was out for so long, and this is just wonderful! Will probably keep ordering from this site!
