Yesterday my granddaughter and I performed a blackberry pie test. We made two pies to deliberately compare the tastes: One pie from wild trailing blackberries and one from wild growing Himalayan blackberries.
We fresh picked Himalaya blackberries from a carefully selected patch free from road dust etc. They were very good tasting right off of the bush. Himalayas are the invasive species of blackberry from Asia that has taken over the PNW. My son calls them “railroad berries” because they are often abundant on railroad rights of way.
We made the other pie from native wild “trailing blackberries” indigenous to the Northwest. These were picked last month and frozen. We used identical ratios of sugar, cinnamon etc.
The wild trailing blackberry pie won by a HUGE margin. I knew that I liked the wild ones better but WOW, they are WAAAAY better. The result surprised me by how strong opinions were, not by what people preferred. We had four first round tasters, two women and two men, ranging in age from age 15 to 71. Someone said that if we only had the Himalaya pie, we'd think that it was good. Also, the Himalayas have so many large seeds that it detracted from the eating pleasure for some tasters, not a problem for some tasters but annoying to others.
