My dad had a large garden, one of the products of which was black raspberries. Mom used to make black raspberry preserves...wonderful! The closest version I have found since is the Old Mill's offering...love 'em. Mom would approve! Keep up the great work and PLEASE start making unadulterated red raspberry preserves again (none of that jalapeno-spiked stuff, please!!)
Always the best!! Buy frequently, but usually in person. Love Black Raspberries!
