How to sprout
Jar, water, windowsill.
Soak two tablespoons overnight. Rinse and drain twice daily in a mesh-lidded jar, out of direct sun. Harvest on day five when leaves turn green. One pound of seed yields roughly fifteen jars.
Full guideWhy sprouts
The numbers are real.
Three-day-old broccoli sprouts contain 10–100× the glucoraphanin of mature broccoli (Fahey, Zhang & Talalay, 1997). Glucoraphanin is the precursor of sulforaphane, among the most studied compounds in cruciferous vegetables.
We cite sources, not claims. Sprouts are food, not medicine.
The variety
Chosen for the jar.
An open-pollinated calabrese type selected for sprouting: fast, even germination and a clean, mild bite. This lot came from a single Idaho grower and passed pathogen screening before it was poured into a pouch.
